linux-2.6

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-2007-2172
  Thomas Graf reported a typo in the IPv4 protocol handler that could
  be used by a local attacker to overrun an array via crafted packets,
  potentially resulting in a Denial of Service (system crash).
  The DECnet counterpart of this issue was already fixed in DSA-1356.
• CVE-2007-2875
  iDefense reported a potential integer underflow in the cpuset filesystem
  which may permit local attackers to gain access to sensitive kernel
  memory. This vulnerability is only exploitable if the cpuset filesystem
  is mounted.
• CVE-2007-3105
  The PaX Team discovered a potential buffer overflow in the random number
  generator which may permit local users to cause a denial of service or
  gain additional privileges. This issue is not believed to effect default
  Debian installations where only root has sufficient privileges to exploit
  it.
• CVE-2007-3843
  A coding error in the CIFS subsystem permits the use of unsigned messages
  even if the client has configured the system to enforce
  signing by passing the sec=ntlmv2i mount option. This may allow remote
  attackers to spoof CIFS network traffic.
• CVE-2007-4308
  Alan Cox reported an issue in the aacraid driver that allows unprivileged
  local users to make ioctl calls which should be restricted to admin
  privileges.

These problems have been fixed in the stable distribution in version
2.6.18.dfsg.1-13etch2.

The following matrix lists additional packages that were rebuilt for
compatibility with or to take advantage of this update:

We recommend that you upgrade your kernel package immediately and reboot
the machine. If you have built a custom kernel from the kernel source
package, you will need to rebuild to take advantage of these fixes.
