MPlayer: Multiple integer overflows

MPlayer: Multiple integer overflows MPlayer is vulnerable to integer overflows in FFmpeg and ASF decoding that could potentially result in the execution of arbitrary code. MPlayer 2006-03-04 2006-06-21 115760 122029 remote 1.0.20060217 1.0_pre8 1.0.20060217

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

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.

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.

There is no known workaround at this time.

All MPlayer users should upgrade to the latest version:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=media-video/mplayer-1.0.20060217"
