Transmission is a cross-platform BitTorrent client.
Transmission mishandles some memory management which may allow manipulation of the heap.
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.
There is no known workaround at this time.
All Transmission users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-p2p/transmission-3.00"
