Ubuntu Security Notice USN-1103-1            April 04, 2011
tex-common vulnerability
CVE-2011-1400
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 10.04 LTS
Ubuntu 10.10

This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.

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

Ubuntu 10.04 LTS:
  tex-common                      2.06ubuntu0.1

Ubuntu 10.10:
  tex-common                      2.08ubuntu0.1

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

Details follow:

Mathias Svensson discovered that the tex-common package contains an
insecure shell_escape_commands configuration item. If a user or automated
system were tricked into opening a specially crafted TeX file, a remote
attacker could execute arbitrary code with user privileges.
