HTTP GlobalLink ActiveX Control Heap BO

Severity: High

This attack could pose a serious security threat. You should take immediate action to stop any damage or prevent further damage from happening.


This signature detects attempts to exploit a heap buffer overflow vulnerability in a GlobalLink ActiveX control.

Additional Information

GlobalLink is prone to a heap-based buffer-overflow vulnerability because it fails to bounds-check user-supplied data before copying it into an insufficiently sized buffer. The issue occurs in the 'ConnectAndEnterRoom()' method of the ActiveX control with CLSID 'AE93C5DF-A990-11D1-AEBD-5254ABDD2B69'.

An attacker can exploit this issue to execute arbitrary code within the context of the affected application. Failed exploit attempts will result in denial-of-service conditions.


  • GlobalLink is affected by this issue; other versions may also be vulnerable.
