Ubuntu Security Notice USN-3263-1
April 21, 2017

freetype vulnerability

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
- Ubuntu 12.04 LTS


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


It was discovered that a heap-based buffer overflow existed in the
FreeType library. 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.
