Technical details
A heap-based out-of-bounds write vulnerability exists in the Gen Digital scanning engine used across multiple antivirus brands. The flaw is triggered when the engine processes a malformed Windows Portable Executable (PE) file. While the attack vector is local, it requires minimal privileges (PR:N) but does require user interaction (UI:R), such as a user or the system attempting to scan the malicious file. Successful exploitation can lead to arbitrary code execution in the context of the antivirus process or a denial-of-service (DoS) by crashing the scanning service. The vulnerability was addressed via a virus definition update (VPS 25040308) rather than a full software version increment.
