freetype vulnerabilities
=========================================================================
A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 15.04
- Ubuntu 14.04 LTS
- Ubuntu 12.04 LTS

Summary:

Several security issues were fixed in FreeType.

Software Description:
- freetype: FreeType 2 is a font engine library

Details:

It was discovered that FreeType did not correctly handle certain malformed
font files. If a user were tricked into using a specially crafted font
file, a remote attacker could cause FreeType to crash or hang, resulting in
a denial of service, or possibly expose uninitialized memory.

Update instructions:

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

Ubuntu 15.04:
  libfreetype6                    2.5.2-2ubuntu3.1

Ubuntu 14.04 LTS:
  libfreetype6                    2.5.2-1ubuntu2.5

Ubuntu 12.04 LTS:
  libfreetype6                    2.4.8-1ubuntu2.3

After a standard system update you need to restart your session to make
all the necessary changes.
