Synopsis ========
MPlayer is vulnerable to integer overflows in FFmpeg and ASF decoding that could potentially result in the execution of arbitrary code.
Background ==========
MPlayer is a media player capable of handling multiple multimedia file formats.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-video/mplayer < 1.0.20060217 >= 1.0.20060217
Description ===========
MPlayer makes use of the FFmpeg library, which is vulnerable to a heap overflow in the avcodec_default_get_buffer() function discovered by Simon Kilvington (see GLSA 200601-06). Furthermore, AFI Security Research discovered two integer overflows in ASF file format decoding, in the new_demux_packet() function from libmpdemux/demuxer.h and the demux_asf_read_packet() function from libmpdemux/demux_asf.c.
Impact ======
An attacker could craft a malicious media file which, when opened using MPlayer, would lead to a heap-based buffer overflow. This could result in the execution of arbitrary code with the permissions of the user running MPlayer.
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-1.0.20060217"
