HTTP: Internet Explorer Gopher Link Embedded in "IMG" Tag
This signature detects attempts to exploit a known vulnerability against Microsoft Internet Explorer using the Gopher protocol. On a Web server, attackers can embed a malicious URL in an image tag, causing a client to visit that URL and become vulnerable to arbitrary code execution.
Extended Description
Microsoft Internet Explorer, Proxy Server and ISA Server includes a gopher client. Reportedly, these clients are vulnerable to a buffer overflow condition. The vulnerability exists in the component that parses gopher replies. A malicious server is able to send a reply that will overflow the buffer and run arbitrary code on a user's system.
