fai-kernels linux-2.6 user-mode-linux - several vulnerabilities

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

• CVE-2007-6282
  Dirk Nehring discovered a vulnerability in the IPsec code that allows
  remote users to cause a denial of service by sending a specially crafted
  ESP packet.
• CVE-2008-0598
  Tavis Ormandy discovered a vulnerability that allows local users to access
  uninitialized kernel memory, possibly leaking sensitive data. This issue
  is specific to the amd64-flavour kernel images.
• CVE-2008-2729
  Andi Kleen discovered an issue where uninitialized kernel memory
  was being leaked to userspace during an exception. This issue may allow
  local users to gain access to sensitive data. Only the amd64-flavour
  Debian kernel images are affected.
• CVE-2008-2812
  Alan Cox discovered an issue in multiple tty drivers that allows
  local users to trigger a denial of service (NULL pointer dereference)
  and possibly obtain elevated privileges.
• CVE-2008-2826
  Gabriel Campana discovered an integer overflow in the sctp code that
  can be exploited by local users to cause a denial of service.
• CVE-2008-2931
  Miklos Szeredi reported a missing privilege check in the do_change_type()
  function. This allows local, unprivileged users to change the properties
  of mount points.
• CVE-2008-3272
  Tobias Klein reported a locally exploitable data leak in the
  snd_seq_oss_synth_make_info() function. This may allow local users
  to gain access to sensitive information.
• CVE-2008-3275
  Zoltan Sogor discovered a coding error in the VFS that allows local users
  to exploit a kernel memory leak resulting in a denial of service.

For the stable distribution (etch), this problem has been fixed in
version 2.6.18.dfsg.1-22etch2.

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