Synopsis
========

An insecure temporary file usage in Muttprint allows for symlink
attacks.

Background
==========

Muttprint formats the output of mail clients to a good-looking printing
using LaTeX.

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

    -------------------------------------------------------------------
     Package             /  Vulnerable  /                   Unaffected
    -------------------------------------------------------------------
  1  app-misc/muttprint     < 0.72d-r1                     >= 0.72d-r1

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

Dmitry E. Oboukhov reported an insecure usage of the temporary file
"/tmp/muttprint.log" in the muttprint script.

Impact
======

A local attacker could perform symlink attacks to overwrite arbitrary
files with the privileges of the user running the application.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Muttprint users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=app-misc/muttprint-0.72d-r1"
