Detail

Synopsis

A vulnerability has been discovered in Ventrilo, allowing for a Denial of Service.

Background

Ventrilo is a Voice over IP group communication server.

Description

Luigi Auriemma reported a NULL pointer dereference in Ventrilo when processing packets with an invalid version number followed by another packet.

Impact

A remote attacker could send specially crafted packets to the server, resulting in a crash.

Workaround

There is no known workaround at this time.

Resolution

All Ventrilo users should upgrade to the latest version:

# emerge --sync

# emerge --ask --oneshot --verbose
">=media-sound/ventrilo-server-bin-3.0.3"
