Signature Detail

HTTP: IncrediMail IMMenuShellExt ActiveX Buffer Overflow

This signature detects attempts to exploit a known vulnerability in IncrediMail IMMenuShellExt ActiveX Control. An attacker can create malicious Web pages containing dangerous ActiveX calls, which if access by a victim, allows the attacker to gain control of the victim's client browser.

Extended Description

IncrediMail is prone to a stack-based buffer-overflow vulnerability because it fails to sufficiently check boundaries of user-supplied input before copying it to an insufficiently sized memory buffer. An attacker may exploit this issue by enticing victims into opening a malicious webpage or HTML email that invokes the affected control. Successful exploits will corrupt process memory, allowing attacker-supplied arbitrary code to run in the context of the client application using the affected ActiveX control.
