Georgi Guninski discovered two Denial of Service vulnerabilities in the Linux kernel.

An integer overflow in the vc_resize() function caused the memory allocation for the new screen being too short, thus causing a buffer overflow and a kernel crash.

There was also a memory leak in the ip_options_get() function. Calling ip_cmsg_send() very often would gradually exhaust memory.

Note: The original advisory (see URL above) also mentions a 'ip_options_get integer overflow'. This was already fixed in USN-38-1 (known as CAN-2004-1016).

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

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

This advisory includes fixes for several security issues :

Petr Vandrovec discovered a flaw in the 32bit emulation code affecting the Linux 2.4 kernel on the AMD64 architecture. A local attacker could use this flaw to gain privileges. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2004-1144 to this issue.

ISEC security research discovered multiple vulnerabilities in the IGMP functionality which was backported in the Red Hat Enterprise Linux 3 kernels. These flaws could allow a local user to cause a denial of service (crash) or potentially gain privileges. Where multicast applications are being used on a system, these flaws may also allow remote users to cause a denial of service. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2004-1137 to this issue.

ISEC security research and Georgi Guninski independently discovered a flaw in the scm_send function in the auxiliary message layer. A local user could create a carefully crafted auxiliary message which could cause a denial of service (system hang). The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2004-1016 to this issue.

A floating point information leak was discovered in the ia64 architecture context switch code. A local user could use this flaw to read register values of other processes by setting the MFH bit. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2004-0565 to this issue.

Kirill Korotaev found a flaw in load_elf_binary affecting kernels prior to 2.4.26. A local user could create a carefully crafted binary in such a way that it would cause a denial of service (system crash).
The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2004-1234 to this issue.

These packages also fix issues in the io_edgeport driver, and a memory leak in ip_options_get.

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

All Red Hat Enterprise Linux 3 users are advised to upgrade their kernels to the packages associated with their machine architectures and configurations as listed in this erratum.

A number of vulnerabilities are fixed in the 2.4 and 2.6 kernels with this advisory :

  - Multiple race conditions in the terminal layer of 2.4     and 2.6 kernels (prior to 2.6.9) can allow a local     attacker to obtain portions of kernel data or allow     remote attackers to cause a kernel panic by switching     from console to PPP line discipline, then quickly     sending data that is received during the switch     (CVE-2004-0814)

  - Richard Hart found an integer underflow problem in the     iptables firewall logging rules that can allow a remote     attacker to crash the machine by using a specially     crafted IP packet. This is only possible, however, if     firewalling is enabled. The problem only affects 2.6     kernels and was fixed upstream in 2.6.8 (CVE-2004-0816)

  - Stefan Esser found several remote DoS confitions in the     smbfs file system. This could be exploited by a hostile     SMB server (or an attacker injecting packets into the     network) to crash the client systems (CVE-2004-0883 and     CVE-2004-0949)

  - Paul Starzetz and Georgi Guninski reported,     independently, that bad argument handling and bad     integer arithmetics in the IPv4 sendmsg handling of     control messages could lead to a local attacker crashing     the machine. The fixes were done by Herbert Xu     (CVE-2004-1016)

  - Rob Landley discovered a race condition in the handling     of /proc/.../cmdline where, under rare circumstances, a     user could read the environment variables of another     process that was still spawning leading to the potential     disclosure of sensitive information such as passwords     (CVE-2004-1058)

  - Paul Starzetz reported that the missing serialization in     unix_dgram_recvmsg() which was added to kernel 2.4.28     can be used by a local attacker to gain elevated (root)     privileges (CVE-2004-1068)

  - Ross Kendall Axe discovered a possible kernel panic     (DoS) while sending AF_UNIX network packets if certain     SELinux-related kernel options were enabled. By default     the CONFIG_SECURITY_NETWORK and CONFIG_SECURITY_SELINUX     options are not enabled (CVE-2004-1069)

  - Paul Starzetz of isec.pl discovered several issues with     the error handling of the ELF loader routines in the     kernel. The fixes were provided by Chris Wright     (CVE-2004-1070, CVE-2004-1071, CVE-2004-1072,     CVE-2004-1073)

  - It was discovered that hand-crafted a.out binaries could     be used to trigger a local DoS condition in both the 2.4     and 2.6 kernels. The fixes were done by Chris Wright     (CVE-2004-1074)

  - Paul Starzetz found bad handling in the IGMP code which     could lead to a local attacker being able to crash the     machine. The fix was done by Chris Wright     (CVE-2004-1137)

  - Jeremy Fitzhardinge discovered two buffer overflows in     the sys32_ni_syscall() and sys32_vm86_warning()     functions that could be used to overwrite kernel memory     with attacker-supplied code resulting in privilege     escalation (CVE-2004-1151)

  - Paul Starzetz found locally exploitable flaws in the     binary format loader's uselib() function that could be     abused to allow a local user to obtain root privileges     (CVE-2004-1235)

  - Paul Starzetz found an exploitable flaw in the page     fault handler when running on SMP machines     (CVE-2005-0001)

  - A vulnerability in insert_vm_struct could allow a locla     user to trigger BUG() when the user created a large vma     that overlapped with arg pages during exec     (CVE-2005-0003)

  - Paul Starzetz also found a number of vulnerabilities in     the kernel binfmt_elf loader that could lead a local     user to obtain elevated (root) privileges     (isec-0017-binfmt_elf)

The provided packages are patched to fix these vulnerabilities. All users are encouraged to upgrade to these updated kernels.

To update your kernel, please follow the directions located at :

http://www.mandrakesoft.com/security/kernelupdate

PLEASE NOTE: Mandrakelinux 10.0 users will need to upgrade to the latest module-init-tools package prior to upgrading their kernel.
Likewise, MNF8.2 users will need to upgrade to the latest modutils package prior to upgrading their kernel.

CAN-2004-0814 :

Vitaly V. Bursov discovered a Denial of Service vulnerability in the 'serio' code; opening the same tty device twice and doing some particular operations on it caused a kernel panic and/or a system lockup. 

Fixing this vulnerability required a change in the Application Binary Interface (ABI) of the kernel. This means that third-party user installed modules might not work any more with the new kernel, so this fixed kernel got a new ABI version number. You have to recompile and reinstall all third-party modules.

CAN-2004-1016 :

Paul Starzetz discovered a buffer overflow vulnerability in the '__scm_send' function which handles the sending of UDP network packets. A wrong validity check of the cmsghdr structure allowed a local attacker to modify kernel memory, thus causing an endless loop (Denial of Service) or possibly even root privilege escalation.

CAN-2004-1056 :

Thomas Hellstrom discovered a Denial of Service vulnerability in the Direct Rendering Manager (DRM) drivers. Due to an insufficient DMA lock checking, any authorized client could send arbitrary values to the video card, which could cause an X server crash or modification of the video output.

CAN-2004-1058 :

Rob Landley discovered a race condition in the handling of /proc/.../cmdline. Under very rare circumstances an user could read the environment variables of another process that was still spawning.
Environment variables are often used to pass passwords and other private information to other processes.

CAN-2004-1068 :

A race condition was discovered in the handling of AF_UNIX network packets. This reportedly allowed local users to modify arbitrary kernel memory, facilitating privilege escalation, or possibly allowing code execution in the context of the kernel.

CAN-2004-1069 :

Ross Kendall Axe discovered a possible kernel panic (causing a Denial of Service) while sending AF_UNIX network packages if the kernel options CONFIG_SECURITY_NETWORK and CONFIG_SECURITY_SELINUX are enabled. This is not the case in the kernel packages shipped in Warty Warthog; however, if you recompiled the kernel using SELinux, you are affected by this flaw.

CAN-2004-1137 :

Paul Starzetz discovered several flaws in the IGMP handling code. This allowed users to provoke a Denial of Service, read kernel memory, and execute arbitrary code with root privileges. This flaw is also exploitable remotely if an application has bound a multicast socket.

CAN-2004-1151 :

Jeremy Fitzhardinge discovered two buffer overflows in the sys32_ni_syscall() and sys32_vm86_warning() functions. This could possibly be exploited to overwrite kernel memory with attacker-supplied code and cause root privilege escalation. 

This vulnerability only affects the amd64 architecture.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Updated kernel packages that fix several security issues in Red Hat Enterprise Linux 2.1 are now available.

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

This advisory includes fixes for the following security issues :

iSEC Security Research discovered a VMA handling flaw in the uselib(2) system call of the Linux kernel. A local user could make use of this flaw to gain elevated (root) privileges. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2004-1235 to this issue.

iSEC Security Research discovered a flaw in the page fault handler code that could lead to local users gaining elevated (root) privileges on multiprocessor machines. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2005-0001 to this issue.

iSEC Security Research and Georgi Guninski independently discovered a flaw in the scm_send function in the auxiliary message layer. A local user could create a carefully crafted auxiliary message which could cause a denial of service (system hang). The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2004-1016 to this issue.

Kirill Korotaev found a flaw in load_elf_binary affecting kernels prior to 2.4.26. A local user could create a carefully crafted binary in such a way that it would cause a denial of service (system crash).
The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2004-1234 to this issue.

These packages also fix issues in the io_edgeport driver (CVE-2004-1017), a memory leak in ip_options_get (CVE-2004-1335), and missing VM_IO flags in some drivers (CVE-2004-1057).

A recent Internet Draft by Fernando Gont recommended that ICMP Source Quench messages be ignored by hosts. A patch to ignore these messages is included.

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.

Several local and remote vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service or the execution of arbitrary code. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2004-0427     A local denial of service vulnerability in do_fork() has     been found.

                                Debian 3.1 (sarge)              Source                        2.4.17-1woody4                  HP Precision architecture     32.5                            Intel IA-64 architecture      011226.18                       IBM S/390 architecture/image  2.4.17-2.woody.5                IBM S/390 architecture/patch  0.0.20020816-0.woody.4          PowerPC architecture (apus)   2.4.17-6                        MIPS architecture             2.4.17-0.020226.2.woody7

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

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

This advisory includes fixes for several security issues :

Petr Vandrovec discovered a flaw in the 32bit emulation code affecting
the Linux 2.4 kernel on the AMD64 architecture. A local attacker could
use this flaw to gain privileges. The Common Vulnerabilities and
Exposures project (cve.mitre.org) has assigned the name CVE-2004-1144
to this issue.

ISEC security research discovered multiple vulnerabilities in the IGMP
functionality which was backported in the Red Hat Enterprise Linux 3
kernels. These flaws could allow a local user to cause a denial of
service (crash) or potentially gain privileges. Where multicast
applications are being used on a system, these flaws may also allow
remote users to cause a denial of service. The Common Vulnerabilities
and Exposures project (cve.mitre.org) has assigned the name
CVE-2004-1137 to this issue.

ISEC security research and Georgi Guninski independantly discovered a
flaw in the scm_send function in the auxiliary message layer. A local
user could create a carefully crafted auxiliary message which could
cause a denial of service (system hang). The Common Vulnerabilities
and Exposures project (cve.mitre.org) has assigned the name
CVE-2004-1016 to this issue.

A floating point information leak was discovered in the ia64
architecture context switch code. A local user could use this flaw to
read register values of other processes by setting the MFH bit. The
Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CVE-2004-0565 to this issue.

Kirill Korotaev found a flaw in load_elf_binary affecting kernels
prior to 2.4.26. A local user could create a carefully crafted binary
in such a way that it would cause a denial of service (system crash).
The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CVE-2004-1234 to this issue.

These packages also fix issues in the io_edgeport driver, and a memory
leak in ip_options_get.

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

All Red Hat Enterprise Linux 3 users are advised to upgrade their
kernels to the packages associated with their machine architectures
and configurations as listed in this erratum.

Updated kernel packages that fix several security issues in Red Hat
Enterprise Linux 2.1 are now available.

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

This advisory includes fixes for the following security issues :

iSEC Security Research discovered a VMA handling flaw in the uselib(2)
system call of the Linux kernel. A local user could make use of this
flaw to gain elevated (root) privileges. The Common Vulnerabilities
and Exposures project (cve.mitre.org) has assigned the name
CVE-2004-1235 to this issue.

iSEC Security Research discovered a flaw in the page fault handler
code that could lead to local users gaining elevated (root) privileges
on multiprocessor machines. The Common Vulnerabilities and Exposures
project (cve.mitre.org) has assigned the name CVE-2005-0001 to this
issue.

iSEC Security Research and Georgi Guninski independently discovered a
flaw in the scm_send function in the auxiliary message layer. A local
user could create a carefully crafted auxiliary message which could
cause a denial of service (system hang). The Common Vulnerabilities
and Exposures project (cve.mitre.org) has assigned the name
CVE-2004-1016 to this issue.

Kirill Korotaev found a flaw in load_elf_binary affecting kernels
prior to 2.4.26. A local user could create a carefully crafted binary
in such a way that it would cause a denial of service (system crash).
The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CVE-2004-1234 to this issue.

These packages also fix issues in the io_edgeport driver
(CVE-2004-1017), a memory leak in ip_options_get (CVE-2004-1335), and
missing VM_IO flags in some drivers (CVE-2004-1057).

A recent Internet Draft by Fernando Gont recommended that ICMP Source
Quench messages be ignored by hosts. A patch to ignore these messages
is included.

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.
