Ubuntu Security Notice USN-1347-1
January 25, 2012

evince vulnerability
==========================================================================

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

- Ubuntu 11.04
- Ubuntu 10.10
- Ubuntu 10.04 LTS

Summary:

Evince could be made to crash or run programs as your login if it opened a
specially crafted file.

Software Description:
- evince: Document viewer

Details:

It was discovered that Evince did not properly parse AFM font files when
processing DVI files. If a user were tricked into opening a specially
crafted DVI file, an attacker could cause Evince to crash or potentially
execute arbitrary code with the privileges of the user invoking the
program.

In the default installation, attackers would be isolated by the Evince
AppArmor profile.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 11.04:
  libevdocument3                  2.32.0-0ubuntu12.4

Ubuntu 10.10:
  libevdocument3                  2.32.0-0ubuntu1.2

Ubuntu 10.04 LTS:
  libevdocument2                  2.30.3-0ubuntu1.3

In general, a standard system update will make all the necessary changes.
