The SUSE Linux Enterprise 10 Service Pack 2 kernel was updated to fix some security issues and various bugs.

The following security problems have been fixed :

  - net/atm/svc.c in the ATM subsystem allowed local users     to cause a denial of service (kernel infinite loop) by     making two calls to svc_listen for the same socket, and     then reading a /proc/net/atm/ *vc file, related to     corruption of the vcc table. (CVE-2008-5079)

  - The __scm_destroy function in net/core/scm.c makes     indirect recursive calls to itself through calls to the     fput function, which allows local users to cause a     denial of service (panic) via vectors related to sending     an SCM_RIGHTS message through a UNIX domain socket and     closing file descriptors. (CVE-2008-5029)

  - Buffer overflow in the hfsplus_find_cat function in     fs/hfsplus/catalog.c allowed attackers to cause a denial     of service (memory corruption or system crash) via an     hfsplus filesystem image with an invalid catalog     namelength field, related to the     hfsplus_cat_build_key_uni function. (CVE-2008-4933)

  - Stack-based buffer overflow in the hfs_cat_find_brec     function in fs/hfs/catalog.c allowed attackers to cause     a denial of service (memory corruption or system crash)     via an hfs filesystem image with an invalid catalog     namelength field, a related issue to CVE-2008-4933.
    (CVE-2008-5025)

  - The inotify functionality might allow local users to     gain privileges via unknown vectors related to race     conditions in inotify watch removal and umount.
    (CVE-2008-5182)

A lot of other bugs were fixed, a detailed list can be found in the RPM changelog.

Updated kernel packages that fix several security issues and multiple bugs are now available for Red Hat Enterprise Linux 3.

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

The kernel packages contain the Linux kernel, the core of any Linux operating system.

Security fixes :

* when fput() was called to close a socket, the __scm_destroy() function in the Linux kernel could make indirect recursive calls to itself. This could, potentially, lead to a denial of service issue.
(CVE-2008-5029, Important)

* the sendmsg() function in the Linux kernel did not block during UNIX socket garbage collection. This could, potentially, lead to a local denial of service. (CVE-2008-5300, Important)

* the exit_notify() function in the Linux kernel did not properly reset the exit signal if a process executed a set user ID (setuid) application before exiting. This could allow a local, unprivileged user to elevate their privileges. (CVE-2009-1337, Important)

* a flaw was found in the Intel PRO/1000 network driver in the Linux kernel. Frames with sizes near the MTU of an interface may be split across multiple hardware receive descriptors. Receipt of such a frame could leak through a validation check, leading to a corruption of the length check. A remote attacker could use this flaw to send a specially crafted packet that would cause a denial of service or code execution. (CVE-2009-1385, Important)

* the ADDR_COMPAT_LAYOUT and MMAP_PAGE_ZERO flags were not cleared when a setuid or setgid program was executed. A local, unprivileged user could use this flaw to bypass the mmap_min_addr protection mechanism and perform a NULL pointer dereference attack, or bypass the Address Space Layout Randomization (ASLR) security feature.
(CVE-2009-1895, Important)

* it was discovered that, when executing a new process, the clear_child_tid pointer in the Linux kernel is not cleared. If this pointer points to a writable portion of the memory of the new program, the kernel could corrupt four bytes of memory, possibly leading to a local denial of service or privilege escalation. (CVE-2009-2848, Important)

* missing initialization flaws were found in getname() implementations in the IrDA sockets, AppleTalk DDP protocol, NET/ROM protocol, and ROSE protocol implementations in the Linux kernel. Certain data structures in these getname() implementations were not initialized properly before being copied to user-space. These flaws could lead to an information leak. (CVE-2009-3002, Important)

* a NULL pointer dereference flaw was found in each of the following functions in the Linux kernel: pipe_read_open(), pipe_write_open(), and pipe_rdwr_open(). When the mutex lock is not held, the i_pipe pointer could be released by other processes before it is used to update the pipe's reader and writer counters. This could lead to a local denial of service or privilege escalation. (CVE-2009-3547, Important)

Bug fixes :

* this update adds the mmap_min_addr tunable and restriction checks to help prevent unprivileged users from creating new memory mappings below the minimum address. This can help prevent the exploitation of NULL pointer dereference bugs. Note that mmap_min_addr is set to zero (disabled) by default for backwards compatibility. (BZ#512642)

* a bridge reference count problem in IPv6 has been fixed. (BZ#457010)

* enforce null-termination of user-supplied arguments to setsockopt().
(BZ#505514)

* the gcc flag '-fno-delete-null-pointer-checks' was added to the kernel build options. This prevents gcc from optimizing out NULL pointer checks after the first use of a pointer. NULL pointer bugs are often exploited by attackers. Keeping these checks is a safety measure. (BZ#511185)

* a check has been added to the IPv4 code to make sure that rt is not NULL, to help prevent future bugs in functions that call ip_append_data() from being exploitable. (BZ#520300)

Users should upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.

Users should upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.

The openSUSE 10.3 kernel was updated to fix various security problems and bugs. Following security bugs were fixed :

CVE-2008-5702: Buffer underflow in the ibwdt_ioctl function in drivers/watchdog/ib700wdt.c might allow local users to have an unknown impact via a certain /dev/watchdog WDIOC_SETTIMEOUT IOCTL call.

CVE-2008-5079: net/atm/svc.c in the ATM subsystem allowed local users to cause a denial of service (kernel infinite loop) by making two calls to svc_listen for the same socket, and then reading a /proc/net/atm/*vc file, related to corruption of the vcc table.

CVE-2008-5029: The __scm_destroy function in net/core/scm.c makes indirect recursive calls to itself through calls to the fput function, which allows local users to cause a denial of service (panic) via vectors related to sending an SCM_RIGHTS message through a UNIX domain socket and closing file descriptors.

CVE-2008-5134: Buffer overflow in the lbs_process_bss function in drivers/net/wireless/libertas/scan.c in the libertas subsystem allowed remote attackers to have an unknown impact via an 'invalid beacon/probe response.'

CVE-2008-4933: Buffer overflow in the hfsplus_find_cat function in fs/hfsplus/catalog.c allowed attackers to cause a denial of service (memory corruption or system crash) via an hfsplus filesystem image with an invalid catalog namelength field, related to the hfsplus_cat_build_key_uni function.

CVE-2008-5025: Stack-based buffer overflow in the hfs_cat_find_brec function in fs/hfs/catalog.c allowed attackers to cause a denial of service (memory corruption or system crash) via an hfs filesystem image with an invalid catalog namelength field, a related issue to CVE-2008-4933.

CVE-2008-5182: The inotify functionality might allow local users to gain privileges via unknown vectors related to race conditions in inotify watch removal and umount.

This update addresses the following security issues :

  - a memory leak in keyctl handling. A local user could use     this flaw to deplete kernel memory, eventually leading     to a denial of service. (CVE-2009-0031, Important)

  - a buffer overflow in the Linux kernel Partial Reliable     Stream Control Transmission Protocol (PR-SCTP)     implementation. This could, potentially, lead to a     denial of service if a Forward-TSN chunk is received     with a large stream ID. (CVE-2009-0065, Important)

  - a flaw when handling heavy network traffic on an SMP     system with many cores. An attacker who could send a     large amount of network traffic could create a denial of     service. (CVE-2008-5713, Important)

  - the code for the HFS and HFS Plus (HFS+) file systems     failed to properly handle corrupted data structures.
    This could, potentially, lead to a local denial of     service. (CVE-2008-4933, CVE-2008-5025, Low)

  - a flaw was found in the HFS Plus (HFS+) file system     implementation. This could, potentially, lead to a local     denial of service when write operations are performed.
    (CVE-2008-4934, Low)

  - when fput() was called to close a socket, the
    __scm_destroy() function in the Linux kernel could make     indirect recursive calls to itself. This could,     potentially, lead to a denial of service issue.
    (CVE-2008-5029, Important)

  - a flaw was found in the Asynchronous Transfer Mode (ATM)     subsystem. A local, unprivileged user could use the flaw     to listen on the same socket more than once, possibly     causing a denial of service. (CVE-2008-5079, Important)

  - a race condition was found in the Linux kernel 'inotify'     watch removal and umount implementation. This could     allow a local, unprivileged user to cause a privilege     escalation or a denial of service. (CVE-2008-5182,     Important)

  - issues affecting NEC/Stratus servers

  - OFED support

  - SELinux

  - various Virtio issues

  - when using the nfsd daemon in a clustered setup, kernel     panics appeared seemingly at random. These panics were     caused by a race condition in the device-mapper mirror     target.

  - the clock_gettime(CLOCK_THREAD_CPUTIME_ID, ) syscall     returned a smaller timespec value than the result of     previous clock_gettime() function execution, which     resulted in a negative, and nonsensical, elapsed time     value.

  - nfs_create_rpc_client was called with a 'flavor'     parameter which was usually ignored and ended up     unconditionally creating the RPC client with an     AUTH_UNIX flavor. This caused problems on AUTH_GSS     mounts when the credentials needed to be refreshed. The     credops did not match the authorization type, which     resulted in the credops dereferencing an incorrect part     of the AUTH_UNIX rpc_auth struct.

  - when copy_user_c terminated prematurely due to reading     beyond the end of the user buffer and the kernel jumped     to the exception table entry, the rsi register was not     cleared. This resulted in exiting back to user code with     garbage in the rsi register.

  - the hexdump data in s390dbf traces was incomplete. The     length of the data traced was incorrect and the SAN     payload was read from a different place then it was     written to.

  - when using connected mode (CM) in IPoIB on ehca2     hardware, it was not possible to transmit any data.

  - when an application called fork() and pthread_create()     many times and, at some point, a thread forked a child     and then attempted to call the setpgid() function, then     this function failed and returned and ESRCH error value.
