USN-1103-1: tex-common vulnerability

04 April 2011

tex-common could be made to run programs as your login if it opened a specially crafted file.

Releases

Packages

  • tex-common - common infrastructure for building and installing TeX

Details

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.

Update instructions

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

Ubuntu 10.10
Ubuntu 10.04

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