Several security issues were fixed in the kernel.

Summary

Several security issues were fixed in the kernel.

Software Description:

- linux-lts-raring: Linux hardware enablement kernel from Raring

Details:

Hannes Frederic Sowa discovered a flaw in the Linux kernel's UDP

flaw to cause a denial of service (system crash) or possibly gain

administrative privileges. (CVE-2013-4470)

Multiple integer overflow flaws were discovered in the Alchemy LCD frame-buffer drivers in the Linux kernel. An unprivileged local user could

Update Instructions

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

Ubuntu 12.04 LTS:
  linux-image-3.8.0-35-generic    3.8.0-35.50~precise1

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.
