Robust fixes for critical security issues in the Ubuntu kernel for EC2, addressing risks of information leaks and DoS.
Several security issues were fixed in the kernel.

Summary

Several security issues were fixed in the kernel.

Software Description:

- linux-ec2: Linux kernel for EC2

Details:

Mathias Krause discovered an information leak in the Linux kernel's ISO

9660 CDROM file system driver. A local user could exploit this flaw to

examine some of the kernel's heap memory. (CVE-2012-6549)

Mathias Krause discovered a flaw in xfrm_user in the Linux kernel. A local

attacker with NET_ADMIN capability could potentially exploit this flaw to

escalate privileges. (CVE-2013-1826)

A buffer overflow was discovered in the Linux Kernel's USB subsystem for

devices reporting the cdc-wdm class. A specially crafted USB device when

plugged-in could cause a denial of service (system crash) or possibly

execute arbitrary code. (CVE-2013-1860)

An information leak was discovered in the Linux kernel's /dev/dvb device. A

local user could exploit this flaw to obtain sensitive information from the

kernel's stack memory. (CVE-2013-1928)

Update Instructions

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

Ubuntu 10.04 LTS:
  linux-image-2.6.32-352-ec2      2.6.32-352.65

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.
