aMule is an eMule-like client for the eD2k and Kademlia networks, supporting multiple platforms.
Sam Hocevar discovered that the aMule preview function does not properly sanitize file names.
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.
There is no known workaround at this time.
All aMule users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-p2p/amule-2.2.5"
