aMule: Parameter injection

Background

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

Description

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

Impact

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

There is no known workaround at this time.

Resolution

All aMule users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=net-p2p/amule-2.2.5"
