iDefense Security Advisory 04.09.10 - Remote exploitation of a heap-based buffer overflow vulnerability in VMware Inc.'s movie decoder allows attackers to execute arbitrary code. This vulnerability exists due to a lack of input validation when processing certain specially crafted Audio-Video Interleave (AVI) files. During processing, a heap buffer will be allocated based on one part of the AVI file data. However, the amount of data copied into that buffer is calculated based on a different part of the file. This leads to an exploitable heap-based buffer overflow condition.
