linux-ec2 vulnerabilities
=========================================================================
A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 10.04 LTS

Summary:

Several security issues were fixed in the kernel.

Software Description:
- linux-ec2: Linux kernel for EC2

Details:

Sasha Levin reported a flaw in the Linux kernel's point-to-point protocol
(PPP) when used with the Layer Two Tunneling Protocol (L2TP). A local user
could exploit this flaw to gain administrative privileges. (CVE-2014-4943)

A flaw was discovered in the Linux kernel's audit subsystem when auditing
certain syscalls. A local attacker could exploit this flaw to obtain
potentially sensitive single-bit values from kernel memory or cause a
denial of service (OOPS). (CVE-2014-3917)

Don Bailey discovered a flaw in the LZO decompress algorithm used by the
Linux kernel. An attacker could exploit this flaw to cause a denial of
service (memory corruption or OOPS). (CVE-2014-4608)

Update instructions:

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

Ubuntu 10.04 LTS:
  linux-image-2.6.32-368-ec2      2.6.32-368.84

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.
