Audacious is a media player that has been forked from Beep Media Player.
Luigi Auriemma has found that the adplug library fails to verify the size of the destination buffers in the unpacking instructions, resulting in various possible heap and buffer overflows.
An attacker can entice a user to load a specially crafted media file, resulting in a crash or possible execution of arbitrary code.
There is no known workaround at this time.
All Audacious users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-sound/audacious-1.1.0"
