graphite2 vulnerabilities

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

- Ubuntu 15.10
- Ubuntu 14.04 LTS


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


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.

  CVE-2016-1521, CVE-2016-1522, CVE-2016-1523, CVE-2016-1526
