Ubuntu Security Announcement USN-2903-1 draws attention to vulnerabilities within libjpeg-turbo and the corresponding implications for system protection.
graphite2 could be made to crash or run programs as your login if it opened a specially crafted font.

Summary

graphite2 could be made to crash or run programs as your login if it

opened a specially crafted font.

Software Description:

- 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 LTS:
  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.
