USN-3398-1: graphite2 vulnerabilities

Publication date

21 August 2017

Overview

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

Releases

Packages

  • graphite2 - Font rendering engine for Complex Scripts

Details

Holger Fuhrmannek and Tyson Smith 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

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.

Learn more about how to get the fixes.

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