Array index error in libmpdemux/demux_mov.c in MPlayer 1.0 rc2 and earlier might allow remote attackers to execute arbitrary code via a QuickTime MOV file with a crafted stsc atom tag.
Multiple integer underflows in the Real demuxer (demux_real.c) in MPlayer 1.0_rc2 and earlier allow remote attackers to cause a denial of service (process termination) and possibly execute arbitrary code via a crafted video file that causes the stream_read function to read or write arbitrary memory.
