USN-1035-1: Evince vulnerabilities

Ubuntu Security Notice USN-1035-1

5th January, 2011

evince vulnerabilities

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

  • Ubuntu 10.10
  • Ubuntu 10.04 LTS
  • Ubuntu 9.10
  • Ubuntu 8.04 LTS

Software description

  • evince

Details

Jon Larimer discovered that Evince's font parsers incorrectly handled
certain buffer lengths when rendering a DVI file. By tricking a user into
opening or previewing a DVI file that uses a specially crafted font file,
an attacker could crash evince or execute arbitrary code with the user's
privileges.

In the default installation of Ubuntu 9.10 and later, attackers would be
isolated by the Evince AppArmor profile.

Update instructions

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

Ubuntu 10.10:
evince 2.32.0-0ubuntu1.1
Ubuntu 10.04 LTS:
evince 2.30.3-0ubuntu1.2
Ubuntu 9.10:
evince 2.28.1-0ubuntu1.3
Ubuntu 8.04 LTS:
evince 2.22.2-0ubuntu2.1

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.
