Multiple integer underflows in the Real demuxer (demuxreal.c) in MPlayer 1.0rc2 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 streamread function to read or write arbitrary memory.

MPlayer allows remote attackers to cause a denial of service (application crash) via (1) a malformed AAC file, as demonstrated by lol-vlc.aac; or (2) a malformed Ogg Media (OGM) file, as demonstrated by lol-ffplay.ogm, different vectors than CVE-2007-6718.
