Important vulnerabilities patched in Ubuntu Linux for EC2 systems via USN-2065-1. Make sure to update your instance to safeguard against potential threats.
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:

Stephan Mueller reported an error in the Linux kernel's ansi cprng random

number generator. This flaw makes it easier for a local attacker to break

cryptographic protections. (CVE-2013-4345)

A flaw was discovered in the Linux kernel's IP Virtual Server (IP_VS)

support. A local user with the CAP_NET_ADMIN capability could exploit this

flaw to gain additional administrative privileges. (CVE-2013-4588)

Nico Golde and Fabian Yamaguchi reported a flaw in the Linux kernel's

debugfs filesystem. An administrative local user could exploit this flaw to

cause a denial of service (OOPS). (CVE-2013-6378)

Nico Golde reported a flaw in the Linux kernel's userspace IO (uio) driver.

A local user could exploit this flaw to cause a denial of service (memory

corruption) or possibly gain privileges. (CVE-2013-6763)

Update Instructions

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

Ubuntu 10.04 LTS:
  linux-image-2.6.32-360-ec2      2.6.32-360.73

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.
