Synopsis
========

A vulnerability has been discovered in po4a, allowing for a symlink
attack.

Background
==========

po4a is a set of tools for helping with the translation of
documentation.

Affected packages
=================

Description
===========

The po4a development team reported a race condition in the gettextize()
function when creating the file "/tmp/gettextization.failed.po".

Impact

A local attacker could perform a symlink attack, possibly overwriting
files with the permissions of the user running po4a.

Workaround
