linux-2.6 - multiple vulnerabilities

Several vulnerabilities have been discovered in the Linux kernel that
may lead to denial of service, privilege escalation, or information
leak. The Common Vulnerabilities and Exposures project identifies the
following problems:

• CVE-2008-4307
  Bryn M. Reeves reported a denial of service in the NFS filesystem.
  Local users can trigger a kernel BUG() due to a race condition in
  the do_setlk function.
• CVE-2008-5395
  Helge Deller discovered a denial of service condition that allows
  local users on PA-RISC to crash the system by attempting to unwind
  a stack containing userspace addresses.
• CVE-2008-5701
  Vlad Malov reported an issue on 64-bit MIPS where a local user
  could cause a system crash by crafting a malicious binary which
  makes o32 syscalls with a number less than 4000.
• CVE-2008-5702
  Zvonimir Rakamaric reported an off-by-one error in the ib700wdt
  watchdog driver which allows local users to cause a buffer
  underflow by making a specially crafted WDIOC_SETTIMEOUT ioctl
  call.
• CVE-2008-5713
  Flavio Leitner discovered that a local user can cause a denial of
  service by generating large amounts of traffic on a large SMP
  system, resulting in soft lockups.
• CVE-2009-0028
  Chris Evans discovered a situation in which a child process can
  send an arbitrary signal to its parent.
• CVE-2009-0029
  Christian Borntraeger discovered an issue effecting the alpha,
  mips, powerpc, s390 and sparc64 architectures that allows local
  users to cause a denial of service or potentially gain elevated
  privileges.
• CVE-2009-0031
  Vegard Nossum discovered a memory leak in the keyctl subsystem
  that allows local users to cause a denial of service by consuming
  all available kernel memory.
• CVE-2009-0065
  Wei Yongjun discovered a memory overflow in the SCTP
  implementation that can be triggered by remote users, permitting
  remote code execution.
• CVE-2009-0322
  Pavel Roskin provided a fix for an issue in the dell_rbu driver
  that allows a local user to cause a denial of service (oops) by
  reading 0 bytes from a sysfs entry.
• CVE-2009-0675
  Roel Kluin discovered inverted logic in the skfddi driver that
  permits local, unprivileged users to reset the driver statistics.
• CVE-2009-0676
  Clement LECIGNE discovered a bug in the sock_getsockopt function
  that may result in leaking sensitive kernel memory.
• CVE-2009-0834
  Roland McGrath discovered an issue on amd64 kernels that allows
  local users to circumvent system call audit configurations which
  filter based on the syscall numbers or argument details.
• CVE-2009-0859
  Jiri Olsa discovered that a local user can cause a denial of
  service (system hang) using a SHM_INFO shmctl call on kernels
  compiled with CONFIG_SHMEM disabled. This issue does not affect
  prebuilt Debian kernels.
• CVE-2009-1192
  Shaohua Li reported an issue in the AGP subsystem that may allow
  local users to read sensitive kernel memory due to a leak of
  uninitialized memory.
• CVE-2009-1265
  Thomas Pollet reported an overflow in the af_rose implementation
  that allows remote attackers to retrieve uninitialized kernel
  memory that may contain sensitive data.
• CVE-2009-1336
  Trond Myklebust reported an issue in the encode_lookup() function
  in the nfs server subsystem that allows local users to cause a
  denial of service (oops in encode_lookup()) by use of a long
  filename.
• CVE-2009-1337
  Oleg Nesterov discovered an issue in the exit_notify function that
  allows local users to send an arbitrary signal to a process by
  running a program that modifies the exit_signal field and then
  uses an exec system call to launch a setuid application.
• CVE-2009-1439
  Pavan Naregundi reported an issue in the CIFS filesystem code that
  allows remote users to overwrite memory via a long
  nativeFileSystem field in a Tree Connect response during mount.

For the oldstable distribution (etch), this problem has been fixed in
version 2.6.18.dfsg.1-24etch2.

We recommend that you upgrade your linux-2.6, fai-kernels, and
user-mode-linux packages.

Note: Debian carefully tracks all known security issues across every
linux kernel package in all releases under active security support.
However, given the high frequency at which low-severity security
issues are discovered in the kernel and the resource requirements of
doing an update, updates for lower priority issues will normally not
be released for all kernels at the same time. Rather, they will be
released in a staggered or “leap-frog” fashion.
