Background

Transmission is a cross-platform BitTorrent client.

Description

Transmission mishandles some memory management which may allow manipulation of the heap.

Impact

A remote attacker could entice a user to open a specially crafted torrent file using Transmission, possibly resulting in execution of arbitrary code with the privileges of the process or a Denial of Service condition.

Workaround

There is no known workaround at this time.

Resolution

All Transmission users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=net-p2p/transmission-3.00"
