4) Description of Vulnerability
Secunia Research has discovered two vulnerabilities in multiple VMWare
products, which can be exploited by malicious people to compromise
a vulnerable system.
The vulnerabilities are caused by two integer truncation errors in
vmnc.dll when processing HexTile encoded video chunks and can be
exploited to cause heap-based buffer overflows.
Successful exploitation may allow execution of arbitrary code by
tricking a user into opening a specially crafted AVI file.
