EIP-2026-116631

This exploit leverages a buffer overflow vulnerability in Yahoo Messenger 8.1 via an ActiveX control (CLSID: 02478D38-C3F9-4EFB-9B51-7695ECA05670) by passing an overly long string argument, causing a remote denial-of-service (DoS). The PoC is minimal but functional, demonstrating the crash condition.
