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.

Security readout for executives and security teams

This issue affects specific legacy Trend Micro consumer security products when the Venus Spy Trap feature is enabled. A local user can crash the security service or potentially run code by creating a file with an overly long path. The bundle does not show internet-facing exposure or confirmed active exploitation. Exposure is limited to systems running Trend Micro AntiSpyware 3.5 or PC-Cillin Internet Security 2007 15.0 through 15.3 with the affected SSAPI Engine and VST enabled. Treat this as a legacy endpoint cleanup issue unless affected products are still present. Urgency rises where shared workstations, kiosks, or low-trust local users can interact with systems running the vulnerable software. Mitigation focus: Check Trend Micro advisory PUB-en-1035845 for vendor-confirmed fixes or configuration guidance.; Inventory and remove affected Trend Micro AntiSpyware and PC-Cillin versions where found.; Confirm the installed SSAPI Engine and vstlib32.dll versions before prioritizing remediation..
