USN-2902-1: graphite2 vulnerabilities

Releases

• Ubuntu 15.10
• Ubuntu 14.04 ESM

Packages

• graphite2 - Font rendering engine for Complex Scripts

Details

Yves Younan 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

• libgraphite2-3 - 1.2.4-3ubuntu1.1

Ubuntu 14.04

• libgraphite2-3 - 1.2.4-1ubuntu1.1

After a standard system update you need to restart applications using
graphite2, such as LibreOffice, to make all the necessary changes.
