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

- 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
