Synopsis

using LaTeX.

Description
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

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

Impact
=3D=3D=3D=3D=3D=3D

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

Workaround
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

There is no known workaround at this time.

Resolution
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

All Muttprint users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=3Dapp-misc/muttprint-0.72d-r1"
