25 January 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

To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.

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