The latest Ubuntu 2046-1 release tackles significant kernel vulnerabilities. Comprehensive information released on OMAP4 security flaws that jeopardize system integrity.
Several security issues were fixed in the kernel.

Summary

Several security issues were fixed in the kernel.

Software Description:

- linux-ti-omap4: Linux kernel for OMAP4

Details:

A flaw was discovered in the Linux kernel's dm snapshot facility. A remote

authenticated user could exploit this flaw to obtain sensitive information

or modify/corrupt data. (CVE-2013-4299)

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

Fragmenttation Offload (UFO). An unprivileged local user could exploit this

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

administrative privileges. (CVE-2013-4470)

Update Instructions

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

Ubuntu 13.04:
  linux-image-3.5.0-236-omap4     3.5.0-236.52

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.
