HTTP JcomSoft AniGIF ActiveX 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 will detect attempts to exploit a buffer overflow vulnerability in JComSoft AniFIG.ocx ActiveX control which may result in remote code execution.

Additional Information

JComSoft Animation GIF ActiveX control is prone to multiple buffer-overflow vulnerabilities because the application fails to perform adequate boundary checks on user-supplied data.

Successfully exploiting these issues may allow remote attackers to execute arbitrary code in the context of the application using the ActiveX control (typically Internet Explorer). Failed exploit attempts will likely result in denial-of-service conditions.


  • Animation GIF ActiveX versions 2.47, 1.12a and 1.12b are vulnerable; other versions may also be affected.
