xine-lib: Buffer overflow

Background

xine-lib is the core library of xine, a multimedia player.

Description

There is a stack based overflow in the libmms library included with xine-lib which can be triggered by malicious use of the send_command, string_utf16, get_data and get_media_packet functions.

Impact

A remote attacker could design a malicious media file that would trigger the overflow, potentially resulting in the execution of arbitrary code.

Workaround

There is no known workaround at this time.

Resolution

All xine-lib users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=media-libs/xine-lib-1.1.2-r2"
