Scroller Ubuntu
A number of security issues were resolved in the Ubuntu linux-lts-quantal kernel version, necessitating prompt system upgrades.
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:

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. (CVE-2013-2237)

Kees Cook discovered flaw in the Human Interface Device (HID) subsystem of

the Linux kernel. A physically proximate attacker could exploit this flaw

to execute arbitrary code or cause a denial of service (heap memory

corruption) via a specially crafted device that provides an invalid Report

ID. (CVE-2013-2888)

Kees Cook discovered a flaw in the Human Interface Device (HID) subsystem

of the Linux kernel when CONFIG_HID_PANTHERLORD is enabled. A physically

Update Instructions

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

Ubuntu 12.04 LTS:
  linux-image-3.8.0-32-generic    3.8.0-32.47~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.
