SSL: Microsoft Internet Explorer SChannel Exploit

This signature detects attempts to exploit a known vulnerability in Internet Explorer. Attackers can create malicious Web pages containing a malformed SSL negotiation, which if accessed by a victim, can allow the attacker to gain control of the victim's client browser.

Extended Description

The Microsoft Windows Schannel security package is prone to a remote code-execution vulnerability. This vulnerability occurs when processing and validating server-sent digital signatures by the client application. A remote attacker could exploit this issue by convincing a victim to visit a malicious website. Remote code execution is possible, but may be extremely difficult. In most cases, denial-of-service conditions will occur.
