Ubuntu Security Notice USN-3398-1

21st August, 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 version:

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

To update your system, please follow these instructions:
https://wiki.ubuntu.com/Security/Upgrades.

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.
