freetype vulnerabilities
==========================================================================

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

- Ubuntu 17.04
- Ubuntu 16.10
- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS

Summary:

FreeType could be made to crash or run programs if it opened a specially
crafted font file.

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, resulting in a
denial of service, or possibly execute arbitrary code.

Update instructions:

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

Ubuntu 17.04:
  libfreetype6                    2.6.3-3ubuntu2.2

Ubuntu 16.10:
  libfreetype6                    2.6.3-3ubuntu1.3

Ubuntu 16.04 LTS:
  libfreetype6                    2.6.1-0.1ubuntu2.3

Ubuntu 14.04 LTS:
  libfreetype6                    2.5.2-1ubuntu2.8

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