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

An input validation error in aMule enables remote attackers to pass
arbitrary parameters to a victim's media player.

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

aMule is an eMule-like client for the eD2k and Kademlia networks,
supporting multiple platforms.

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

    -------------------------------------------------------------------
     Package        /  Vulnerable  /                        Unaffected
    -------------------------------------------------------------------
  1  net-p2p/amule       < 2.2.5                              >=3D 2.2.5

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

Sam Hocevar discovered that the aMule preview function does not
properly sanitize file names.

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

A remote attacker could entice a user to download a file with a
specially crafted file name to inject arbitrary arguments to the
victim's video player.

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 aMule users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose =3Dnet-p2p/amule-2.2.5
