Ubuntu Security Notice USN-1318-1
January 05, 2012

linux-fsl-imx51 vulnerabilities
==========================================================================

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

- Ubuntu 10.04 LTS

Summary:

Several security issues were fixed in the kernel.

Software Description:
- linux-fsl-imx51: Linux kernel for IMX51

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 10.04 LTS:
  linux-image-2.6.31-612-imx51    2.6.31-612.32

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.
