Ubuntu Security Notice USN-1651-1
November 30, 2012

linux vulnerability
============================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 10.04 LTS

Summary:

The system could be made to crash under certain conditions.

Software Description:
- linux: Linux kernel

Details:

Rodrigo Freire discovered a flaw in the Linux kernel's TCP illinois
congestion control algorithm. A local attacker could use this to cause a
denial of service.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 10.04 LTS:
  linux-image-2.6.32-45-386       2.6.32-45.100
  linux-image-2.6.32-45-generic   2.6.32-45.100
  linux-image-2.6.32-45-generic-pae  2.6.32-45.100
  linux-image-2.6.32-45-ia64      2.6.32-45.100
  linux-image-2.6.32-45-lpia      2.6.32-45.100
  linux-image-2.6.32-45-powerpc   2.6.32-45.100
  linux-image-2.6.32-45-powerpc-smp  2.6.32-45.100
  linux-image-2.6.32-45-powerpc64-smp  2.6.32-45.100
  linux-image-2.6.32-45-preempt   2.6.32-45.100
  linux-image-2.6.32-45-server    2.6.32-45.100
  linux-image-2.6.32-45-sparc64   2.6.32-45.100
  linux-image-2.6.32-45-sparc64-smp  2.6.32-45.100
  linux-image-2.6.32-45-versatile  2.6.32-45.100
  linux-image-2.6.32-45-virtual   2.6.32-45.100

After a standard system update you need to reboot your computer to make
all the necessary changes.

ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed. If
you use linux-restricted-modules, you have to update that package as
well to get modules which work with the new kernel version. Unless you
manually uninstalled the standard kernel metapackages (e.g. linux-generic,
linux-server, linux-powerpc), a standard system upgrade will automatically
perform this as well.
