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.

Heap-based buffer overflow in libmpdemux/aviheader.c in MPlayer 1.0rc1 and earlier allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a .avi file with certain large "indx truck size" and nEntriesInuse values, and a certain wLongsPerEntry value.

Multiple stack-based buffer overflows in stream/stream_cddb.c in MPlayer before 1.0rc1try3 allow remote attackers to execute arbitrary code via a CDDB entry with a long (1) album title or (2) category.

Heap-based buffer overflow in the pnm_get_chunk function for xine 0.99.2, and other packages such as MPlayer that use the same code, allows remote attackers to execute arbitrary code via long PNA_TAG values, a different vulnerability than CVE-2004-1188.

The pnm_get_chunk function in xine 0.99.2 and earlier, and other packages such as MPlayer that use the same code, does not properly verify that the chunk size is less than the PREAMBLE_SIZE, which causes a read operation with a negative length that leads to a buffer overflow via (1) RMF_TAG, (2) DATA_TAG, (3) PROP_TAG, (4) MDPR_TAG, and (5) CONT_TAG values, a different vulnerability than CVE-2004-1187.
