Detailsinfo

A vulnerability, which was classified as critical, has been found in Trend Micro PC-Cillin Internet Security 2007 up to 15.2. This issue affects an unknown functionality in the library vstlib32.dll. The manipulation with an unknown input leads to a stack-based overflow vulnerability. Using CWE to declare the problem leads to CWE-121. A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Stack-based buffer overflow in vstlib32.dll 1.2.0.1012 in the SSAPI Engine 5.0.0.1066 through 5.2.0.1012 in Trend Micro AntiSpyware 3.5 and PC-Cillin Internet Security 2007 15.0 through 15.3, when the Venus Spy Trap (VST) feature is enabled, allows local users to cause a denial of service (service crash) or execute arbitrary code via a file with a long pathname, which triggers the overflow during a ReadDirectoryChangesW callback notification.

The weakness was shared 08/22/2007 by Ismael Briones (Website). It is possible to read the advisory at securitytracker.com. The identification of this vulnerability is CVE-2007-3873 since 07/18/2007. Attacking locally is a requirement. No form of authentication is needed for a successful exploitation. Technical details of the vulnerability are known, but there is no available exploit.
