Multiple integer overflows in xine-lib 1.1.11 and earlier allow remote attackers to trigger heap-based buffer overflows and possibly execute arbitrary code via (1) a crafted .FLV file, which triggers an overflow in demuxers/demux_flv.c; (2) a crafted .MOV file, which triggers an overflow in demuxers/demux_qt.c; (3) a crafted .RM file, which triggers an overflow in demuxers/demux_real.c; (4) a crafted .MVE file, which triggers an overflow in demuxers/demux_wc3movie.c; (5) a crafted .MKV file, which triggers an overflow in demuxers/ebml.c; or (6) a crafted .CAK file, which triggers an overflow in demuxers/demux_film.c.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
