Scroller Ubuntu
Tackling weaknesses in graphite2 that may lead to system failures or permit unauthorized code execution.
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:

It was 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                  1.3.6-1ubuntu0.15.10.1

Ubuntu 14.04 LTS:
  libgraphite2-3                  1.3.6-1ubuntu0.14.04.1

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.
