Synopsis
=3D=3D=3D=3D=3D=3D=3D=3D

Amarok uses temporary files in an insecure manner, allowing for a
symlink attack.

Background
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

Amarok is an advanced music player.

Affected packages
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

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

Dwayne Litzenberger reported that the
MagnatuneBrowser::listDownloadComplete() function in
magnatunebrowser/magnatunebrowser.cpp uses the album_info.xml temporary
file in an insecure manner.

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

A local attacker could perform a symlink attack to overwrite arbitrary
files on the system 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 Amarok users should upgrade to the latest version:

      # emerge --sync
      # emerge --ask --oneshot --verbose ">=3Dmedia-sound/amarok-1.4.10"
