USN-2927-1: graphite2 vulnerabilities

14 March 2016

graphite2 could be made to crash or run programs as your login if it opened a specially crafted font.

Releases

Packages

  • graphite2 - Font rendering engine for Complex Scripts

Details

It was discovered that graphite2 incorrectly handled certain malformed
fonts. If a user or automated system were tricked into opening a specially-
crafted font file, a remote attacker could use this issue to cause
graphite2 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 15.10
Ubuntu 14.04

This update uses a new upstream release, which includes additional bug
fixes. After a standard system update you need to restart applications
using graphite2, such as LibreOffice, to make all the necessary changes.
