Ubuntu Security Notice USN-3398-1
August 21, 2017

graphite2 vulnerabilities
==========================================================================

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

- Ubuntu 17.04
- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS

Summary:

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

Software Description:
- 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:

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

Ubuntu 17.04:
libgraphite2-3 1.3.10-0ubuntu0.17.04.1

Ubuntu 16.04 LTS:
libgraphite2-3 1.3.10-0ubuntu0.16.04.1

Ubuntu 14.04 LTS:
libgraphite2-3 1.3.10-0ubuntu0.14.04.1

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.
