Ubuntu 12.04 LTS USN-1993-1 moderate: kernel information leak

ubuntu
Calendar Grey October 22, 2013
Scroller Ubuntu
A flaw in the Linux kernel potentially reveals confidential data to local users. Ensure your Ubuntu 12.04 system is updated to access the latest security patch.
The system could be made to expose sensitive information to a local user.

Summary

The system could be made to expose sensitive information to a local user.

Software Description:

- linux-ti-omap4: Linux kernel for OMAP4

Details:

An information leak was discovered in the Linux kernel when reading

broadcast messages from the notify_policy interface of the IPSec

key_socket. A local user could exploit this flaw to examine potentially

sensitive information in kernel memory.

Update Instructions

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

Ubuntu 12.04 LTS:
  linux-image-3.2.0-1439-omap4    3.2.0-1439.58

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.
