Signature Detail

HTTP: JComSoft AniGIF.ocx Unsafe ActiveX Control

This signature detects attempts to use unsafe ActiveX controls in JComSoft. An attacker can create a malicious Web site containing Web pages with dangerous ActiveX controls, which if accessed by a victim, allows the attacker to gain control of the victim's client browser, resulting in a user-level arbitrary code execution.

Extended Description

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

Affected Products

• JComSoft Animation GIF ActiveX 1.12a
• JComSoft Animation GIF ActiveX 1.12b
• JComSoft Animation GIF ActiveX 2.4.7
• SpeedBit Download Accelerator Plus 6.8
