DNS: Internet Explorer Hostname Overflow
This signature detects attempts to exploit a known vulnerability against Internet Explorer due to the way it handles certain URLs. An attacker can construct a malicious Web page, which can potentially allow remote code execution if a user visited this Web site or viewed a malicious e-mail message. An attacker could take complete control of an affected system. However, user interaction is required to exploit this vulnerability.
Extended Description
A buffer overflow vulnerability is reported in Microsoft Internet Explorer. This issue is due to insufficient boundary verification of user-supplied input data causing a fixed-sized memory buffer to be overrun when attempting to copy data into it. This vulnerability allows attacker-supplied machine code to be executed in the context of the affected application.
