mpg123: Buffer overflow

Background

mpg123 is a real-time MPEG audio player.

Description

mpg123 improperly parses frame headers in input streams.

Impact

By inducing a user to play a malicious file, an attacker may be able to exploit a buffer overflow to execute arbitrary code with the permissions of the user running mpg123.

Workaround

There is no known workaround at this time.

Resolution

All mpg123 users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=media-sound/mpg123-0.59s-r9"
