MPlayer: Multiple overflows

Background

MPlayer is a media player capable of handling multiple multimedia file formats.

Description

iDEFENSE, Ariel Berkman and the MPlayer development team found multiple vulnerabilities in MPlayer. These include potential heap overflows in Real RTSP and pnm streaming code, stack overflows in MMST streaming code and multiple buffer overflows in BMP demuxer and mp3lib code.

Impact

A remote attacker could craft a malicious file or design a malicious streaming server. Using MPlayer to view this file or connect to this server could trigger an overflow and execute attacker-controlled code.

Workaround

There is no known workaround at this time.

Resolution

All MPlayer users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=media-video/mplayer-1.0_pre5-r5"
