Security Alert USN-1341-1 presents vital kernel enhancements for Ubuntu, addressing several vulnerabilities. Ensure your safety!
Several security issues were fixed in the kernel.

Summary

Several security issues were fixed in the kernel.

Software Description:

- linux: Linux kernel

Details:

Peter Huewe discovered an information leak in the handling of reading

security-related TPM data. A local, unprivileged user could read the

results of a previous TPM command. (CVE-2011-1162)

Clement Lecigne discovered a bug in the HFS filesystem. A local attacker

could exploit this to cause a kernel oops. (CVE-2011-2203)

A flaw was found in how the Linux kernel handles user-defined key types. An

unprivileged local user could exploit this to crash the system.

(CVE-2011-4110)

Update Instructions

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

Ubuntu 10.10:
  linux-image-2.6.35-32-generic   2.6.35-32.64
  linux-image-2.6.35-32-generic-pae  2.6.35-32.64
  linux-image-2.6.35-32-omap      2.6.35-32.64
  linux-image-2.6.35-32-powerpc   2.6.35-32.64
  linux-image-2.6.35-32-powerpc-smp  2.6.35-32.64
  linux-image-2.6.35-32-powerpc64-smp  2.6.35-32.64
  linux-image-2.6.35-32-server    2.6.35-32.64
  linux-image-2.6.35-32-versatile  2.6.35-32.64
  linux-image-2.6.35-32-virtual   2.6.35-32.64

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.
