Updated kernel packages that fix several security issues in the Red Hat Enterprise Linux 3 kernel are now available.

This security advisory has been rated as having important security impact by the Red Hat Security Response Team.

The Linux kernel handles the basic functions of the operating system.

The following security issues were fixed :

The Vicam USB driver did not use the copy_from_user function to access userspace, crossing security boundaries. (CVE-2004-0075)

The ext3 and jfs code did not properly initialize journal descriptor blocks. A privileged local user could read portions of kernel memory.
(CVE-2004-0177)

The terminal layer did not properly lock line discipline changes or pending IO. An unprivileged local user could read portions of kernel memory, or cause a denial of service (system crash). (CVE-2004-0814)

A race condition was discovered. Local users could use this flaw to read the environment variables of another process that is still spawning via /proc/.../cmdline. (CVE-2004-1058)

A flaw in the execve() syscall handling was discovered, allowing a local user to read setuid ELF binaries that should otherwise be protected by standard permissions. (CVE-2004-1073). Red Hat originally reported this as being fixed by RHSA-2004:549, but the associated fix was missing from that update.

Keith Owens reported a flaw in the Itanium unw_unwind_to_user() function. A local user could use this flaw to cause a denial of service (system crash) on the Itanium architecture. (CVE-2005-0135)

A missing Itanium syscall table entry could allow an unprivileged local user to cause a denial of service (system crash) on the Itanium architecture. (CVE-2005-0137)

A flaw affecting the OUTS instruction on the AMD64 and Intel EM64T architectures was discovered. A local user could use this flaw to access privileged IO ports. (CVE-2005-0204)

A flaw was discovered in the Linux PPP driver. On systems allowing remote users to connect to a server using ppp, a remote client could cause a denial of service (system crash). (CVE-2005-0384)

A flaw in the Red Hat backport of NPTL to Red Hat Enterprise Linux 3 was discovered that left a pointer to a freed tty structure. A local user could potentially use this flaw to cause a denial of service (system crash) or possibly gain read or write access to ttys that should normally be prevented. (CVE-2005-0403)

A flaw in fragment queuing was discovered affecting the netfilter subsystem. On systems configured to filter or process network packets (for example those configured to do firewalling), a remote attacker could send a carefully crafted set of fragmented packets to a machine and cause a denial of service (system crash). In order to sucessfully exploit this flaw, the attacker would need to know (or guess) some aspects of the firewall ruleset in place on the target system to be able to craft the right fragmented packets. (CVE-2005-0449)

Missing validation of an epoll_wait() system call parameter could allow a local user to cause a denial of service (system crash) on the IBM S/390 and zSeries architectures. (CVE-2005-0736)

A flaw when freeing a pointer in load_elf_library was discovered. A local user could potentially use this flaw to cause a denial of service (system crash). (CVE-2005-0749)

A flaw was discovered in the bluetooth driver system. On system where the bluetooth modules are loaded, a local user could use this flaw to gain elevated (root) privileges. (CVE-2005-0750)

In addition to the security issues listed above, there was an important fix made to the handling of the msync() system call for a particular case in which the call could return without queuing modified mmap()'ed data for file system update. (BZ 147969)

Note: The kernel-unsupported package contains various drivers and modules that are unsupported and therefore might contain security problems that have not been addressed.

Red Hat Enterprise Linux 3 users are advised to upgrade their kernels to the packages associated with their machine architectures/configurations

Please note that the fix for CVE-2005-0449 required changing the external symbol linkages (kernel module ABI) for the ip_defrag() and ip_ct_gather_frags() functions. Any third-party module using either of these would also need to be fixed.

Updated kernel packages that fix several security issues are now available for Red Hat Enterprise Linux 4.

This update has been rated as having important security impact by the Red Hat Security Response Team.

[Updated 9 August 2005] The advisory text has been updated to show that this update fixed the security issue named CVE-2005-0210 but not CVE-2005-0209. The issue CVE-2005-0209 was actually fixed by RHSA-2005:420. No changes have been made to the packages associated with this advisory.

The Linux kernel handles the basic functions of the operating system.

A flaw in the fib_seq_start function was discovered. A local user could use this flaw to cause a denial of service (system crash) via /proc/net/route. (CVE-2005-1041)

A flaw in the tmpfs file system was discovered. A local user could use this flaw to cause a denial of service (system crash). (CVE-2005-0977)

A flaw was discovered in the Linux PPP driver. On systems allowing remote users to connect to a server using ppp, a remote client could cause a denial of service (system crash). (CVE-2005-0384)

A flaw was discovered in the ext2 file system code. When a new directory is created, the ext2 block written to disk is not initialized, which could lead to an information leak if a disk image is made available to unprivileged users. (CVE-2005-0400)

A flaw in fragment queuing was discovered that affected the Linux kernel netfilter subsystem. On systems configured to filter or process network packets (e.g. firewalling), a remote attacker could send a carefully crafted set of fragmented packets to a machine and cause a denial of service (system crash). In order to sucessfully exploit this flaw, the attacker would need to know or guess some aspects of the firewall ruleset on the target system. (CVE-2005-0449)

A number of flaws were found in the Linux 2.6 kernel. A local user could use these flaws to read kernel memory or cause a denial of service (crash). (CVE-2005-0529, CVE-2005-0530, CVE-2005-0531)

    Please note that

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Multiple vulnerabilities in the Linux kernel have been discovered and fixed in this update. The following CVE names have been fixed in the LE2005 kernel :

Colin Percival discovered a vulnerability in Intel's Hyper-Threading technology could allow a local user to use a malicious thread to create covert channels, monitor the execution of other threads, and obtain sensitive information such as cryptographic keys via a timing attack on memory cache misses. This has been corrected by disabling HT support in all kernels (CVE-2005-0109).

An information leak in the ext2 filesystem code in kernels prior to 2.6.11.6 was found where when a new directory is created, the ext2 block written to disk is not initialized (CVE-2005-0400).

A flaw when freeing a pointer in load_elf_library was found in kernels prior to 2.6.11.6 that could be abused by a local user to potentially crash the machine causing a Denial of Service (CVE-2005-0749).

A problem with the Bluetooth kernel stack in kernels 2.4.6 through 2.4.30-rc1 and 2.6 through 2.6.11.5 could be used by a local attacker to gain root access or crash the machine (CVE-2005-0750).

Paul Starzetz found an integer overflow in the ELF binary format loader's code dump function in kernels prior to and including 2.4.31-pre1 and 2.6.12-rc4. By creating and executing a specially crafted ELF executable, a local attacker could exploit this to execute arbitrary code with root and kernel privileges (CVE-2005-1263).

The drivers for raw devices used the wrong function to pass arguments to the underlying block device in 2.6.x kernels. This made the kernel address space accessible to user-space applications allowing any local user with at least read access to a device in /dev/raw/* (usually only root) to execute arbitrary code with kernel privileges (CVE-2005-1264).

The it87 and via686a hardware monitor drivers in kernels prior to 2.6.11.8 and 2.6.12 prior to 2.6.12-rc2 created a sysfs file named 'alarms' with write permissions although they are not designed to be writable. This allowed a local user to crash the kernel by attempting to write to these files (CVE-2005-1369).

In addition to the above-noted CVE-2005-0109, CVE-2005-0400, CVE-2005-0749, CVE-2005-0750, and CVE-2005-1369 fixes, the following CVE names have been fixed in the 10.1 kernel :

The POSIX Capability Linux Security Module (LSM) for 2.6 kernels up to and including 2.6.8.1 did not properly handle the credentials of a process that is launched before the module is loaded, which could be used by local attackers to gain elevated privileges (CVE-2004-1337).

A flaw in the Linux PPP driver in kernel 2.6.8.1 was found where on systems allowing remote users to connect to a server via PPP, a remote client could cause a crash, resulting in a Denial of Service (CVE-2005-0384).

George Guninski discovered a buffer overflow in the ATM driver in kernels 2.6.10 and 2.6.11 before 2.6.11-rc4 where the atm_get_addr() function does not validate its arguments sufficiently which could allow a local attacker to overwrite large portions of kernel memory by supplying a negative length argument. This could potentially lead to the execution of arbitrary code (CVE-2005-0531).

The reiserfs_copy_from_user_to_file_region function in reiserfs/file.c before kernel 2.6.11, when running on 64-bit architectures, could allow local users to trigger a buffer overflow as a result of casting discrepancies between size_t and int data types. This could allow an attacker to overwrite kernel memory, crash the machine, or potentially obtain root access (CVE-2005-0532).

A race condition in the Radeon DRI driver in kernel 2.6.8.1 allows a local user with DRI privileges to execute arbitrary code as root (CVE-2005-0767).

Access was not restricted to the N_MOUSE discipline for a TTY in kernels prior to 2.6.11. This could allow local attackers to obtain elevated privileges by injecting mouse or keyboard events into other user's sessions (CVE-2005-0839).

Some futex functions in futex.c in 2.6 kernels performed get_user calls while holding the mmap_sem semaphore, which could allow a local attacker to cause a deadlock condition in do_page_fault by triggering get_user faults while another thread is executing mmap or other functions (CVE-2005-0937).

In addition to the above-noted CVE-2004-1337, CVE-2005-0109, CVE-2005-0384, CVE-2005-0400, CVE-2005-0531, CVE-2005-0532, CVE-2005-0749, CVE-2005-0750, CVE-2005-0767, CVE-2005-0839, CVE-2005-0937, CVE-2005-1263, CVE-2005-1264, and CVE-2005-1369 fixes, the following CVE names have been fixed in the 10.0/ Corporate 3.0 kernels :

A race condition in the setsid function in kernels before 2.6.8.1 could allow a local attacker to cause a Denial of Service and possibly access portions of kernel memory related to TTY changes, locking, and semaphores (CVE-2005-0178).

When forwarding fragmented packets in kernel 2.6.8.1, a hardware assisted checksum could only be used once which could lead to a Denial of Service attack or crash by remote users (CVE-2005-0209).

A signedness error in the copy_from_read_buf function in n_tty.c before kernel 2.6.11 allows local users to read kernel memory via a negative argument (CVE-2005-0530).

A vulnerability in the fib_seq_start() function allowed a local user to crash the system by readiung /proc/net/route in a certain way, causing a Denial of Service (CVE-2005-1041).

A vulnerability in the Direct Rendering Manager (DRM) driver in the 2.6 kernel does not properly check the DMA lock, which could allow remote attackers or local users to cause a Denial of Service (X Server crash) and possibly modify the video output (CVE-2004-1056).

Multiple vulnerabilities in the Linux kernel have been discovered and fixed in this update. The following have been fixed in the 2.4 kernels :

Colin Percival discovered a vulnerability in Intel's Hyper-Threading technology could allow a local user to use a malicious thread to create covert channels, monitor the execution of other threads, and obtain sensitive information such as cryptographic keys via a timing attack on memory cache misses. This has been corrected by disabling HT support in all kernels (CVE-2005-0109).

When forwarding fragmented packets, a hardware assisted checksum could only be used once which could lead to a Denial of Service attack or crash by remote users (CVE-2005-0209).

A flaw in the Linux PPP driver was found where on systems allowing remote users to connect to a server via PPP, a remote client could cause a crash, resulting in a Denial of Service (CVE-2005-0384).

An information leak in the ext2 filesystem code was found where when a new directory is created, the ext2 block written to disk is not initialized (CVE-2005-0400).

A signedness error in the copy_from_read_buf function in n_tty.c allows local users to read kernel memory via a negative argument (CVE-2005-0530).

George Guninski discovered a buffer overflow in the ATM driver where the atm_get_addr() function does not validate its arguments sufficiently which could allow a local attacker to overwrite large portions of kernel memory by supplying a negative length argument.
This could potentially lead to the execution of arbitrary code (CVE-2005-0531).

A flaw when freeing a pointer in load_elf_library was found that could be abused by a local user to potentially crash the machine causing a Denial of Service (CVE-2005-0749).

A problem with the Bluetooth kernel stack in kernels 2.4.6 through 2.4.30-rc1 and 2.6 through 2.6.11.5 could be used by a local attacker to gain root access or crash the machine (CVE-2005-0750).

A race condition in the Radeon DRI driver allows a local user with DRI privileges to execute arbitrary code as root (CVE-2005-0767).

Paul Starzetz found an integer overflow in the ELF binary format loader's code dump function in kernels prior to and including 2.4.31-pre1 and 2.6.12-rc4. By creating and executing a specially crafted ELF executable, a local attacker could exploit this to execute arbitrary code with root and kernel privileges (CVE-2005-1263).

The remote host is missing the patch for the advisory SUSE-SA:2005:021 (kernel).


This Linux kernel security update fixes a problem within the Bluetooth kernel stack which can be used by a local attacker to gain root access or crash the machine.

To exploit this problem, the Bluetooth modules do not need to be loaded since they are auto loaded on demand (except in products mentioned below).

This problem has been assigned the Mitre CVE ID CVE-2005-0750.

Updated packages have been provided for the default affected products:
- SUSE Linux 8.2, 9.0 and 9.2 (both i386 and x86_64) - SUSE Linux Enterprise Server 8 (i386, ia64 and x86_64) - SUSE Linux Desktop 1.0

Other architectures do not have Bluetooth enabled.
Also SUSE Linux 9.1, SUSE Linux Enterprise Server 9 and Novell Linux Desktop 9 are not affected by default since the Bluetooth module is not auto loaded. These will get the patch with the next security update.

Updated kernel packages are now available as part of ongoing support and maintenance of Red Hat Enterprise Linux version 2.1. This is the seventh regular update.

This security advisory has been rated as having important security impact by the Red Hat Security Response Team.

The Linux kernel handles the basic functions of the operating system.

This is the seventh regular kernel update to Red Hat Enterprise Linux 2.1

The following security updates were made :

A flaw in fragment queuing was discovered that affected the Linux 2.4 and Linux 2.6 kernel netfilter subsystem. On systems configured to filter or process network packets (for example those configured to do firewalling), a remote attacker could send a carefully crafted set of fragmented packets to a machine and cause a denial of service (system crash). In order to sucessfully exploit this flaw, the attacker would need to know (or guess) some aspects of the firewall ruleset in place on the target system to be able to craft the right fragmented packets.
(CVE-2005-0449)

A flaw was discovered in the Linux PPP driver. On systems allowing remote users to connect to a server using ppp, a remote client could cause a denial of service (system crash). (CVE-2005-0384)

A flaw was discovered in the bluetooth driver system. On system where the bluetooth modules are loaded, a local user could use this flaw to gain elevated (root) privileges. (CVE-2005-0750)

An integer overflow flaw was discovered in the ubsec_keysetup function in the Broadcom 5820 cryptonet driver. On systems using this driver, a local user could cause a denial of service (crash) or possibly gain elevated privileges. (CVE-2004-0619) Please note that this update contains an unpatched kernel module called bcm5820_old for backwards compatibility which is still vulnerable to CVE-2004-0619.

The following device drivers have been updated to new versions :

mptfusion: 2.05.16 -> 2.05.16.02 bcm5820: 1.17 -> 1.81 cciss: 2.4.52
-> 2.4.54 qla2x00: 6.04.01 -> 7.01.01

There were many bug fixes in various parts of the kernel. The ongoing effort to resolve these problems has resulted in a marked improvement in the reliability and scalability of Red Hat Enterprise Linux 2.1.

Bug fixes include: - Fixes an incorrect and ever-changing physical_id field in /proc/cpuinfo. - Now recognizes a particular e1000 device (PCI ID 8086:1014) - Fixes a panic in disk quota code - Fixes a bug in which msync(...MS_SYNC) returns before the data is written to disk - Adds new devices to the SCSI scan list so they can be initialized and handled properly: LSI ProFibre 4000R, HP HSV200/210, HP MSA, STK OPENstorage D178. - Fixes a potential format overflow in /proc/partitions - Restores module parameters to the e100 driver for compatibility with existing customer scripts. - Fixes a bug in which cat'ing /proc/mdstat while adding/removing devices can cause a kernel oops

All Red Hat Enterprise Linux 2.1 users are advised to upgrade their kernels to the packages associated with their machine architectures and configurations as listed in this erratum.

Please note that a vulnerability addressed by this update (CVE-2005-0449) required a change to the kernel module ABI which could cause third party modules to not work. However, Red Hat is currently not aware of any module that would be affected by this change.

Mathieu Lafon discovered an information leak in the ext2 file system driver. When a new directory was created, the ext2 block written to disk was not initialized, so that previous memory contents (which could contain sensitive data like passwords) became visible on the raw device. This is particularly important if the target device is removable and thus can be read by users other than root.
(CAN-2005-0400)

Yichen Xie discovered a Denial of Service vulnerability in the ELF loader. A specially crafted ELF library or executable could cause an attempt to free an invalid pointer, which lead to a kernel crash.
(CAN-2005-0749)

Ilja van Sprundel discovered that the bluez_sock_create() function did not check its 'protocol' argument for negative values. A local attacker could exploit this to execute arbitrary code with root privileges by creating a Bluetooth socket with a specially crafted protocol number. (CAN-2005-0750)

Michal Zalewski discovered that the iso9660 file system driver fails to check ranges properly in several cases. Mounting a specially crafted CD-ROM may have caused a buffer overflow leading to a kernel crash or even arbitrary code execution. (CAN-2005-0815)

Previous kernels did not restrict the use of the N_MOUSE line discipline in the serial driver. This allowed an unprivileged user to inject mouse movement and/or keystrokes (using the sunkbd driver) into the input subsystem, taking over the console or an X session, where another user is logged in. (CAN-2005-0839)

A Denial of Service vulnerability was found in the tmpfs driver, which is commonly used to mount RAM disks below /dev/shm and /tmp. The shm_nopage() did not properly verify its address argument, which could be exploited by a local user to cause a kernel crash with invalid addresses.
