The pnmgetchunk 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 PREAMBLESIZE, which causes a read operation with a negative length that leads to a buffer overflow via (1) RMFTAG, (2) DATATAG, (3) PROPTAG, (4) MDPRTAG, and (5) CONTTAG values, a different vulnerability than CVE-2004-1187.

Buffer overflow in the openaifffile function in demuxaiff.c for xine-lib (libxine) 1-rc7 allows remote attackers to execute arbitrary code via a crafted AIFF file.

Heap-based buffer overflow in the pnmgetchunk 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 PNATAG values, a different vulnerability than CVE-2004-1188.
