Microsoft IIS FTPd NLST Remote Buffer Overflow Vulnerability

Microsoft IIS is prone to a remote stack-based buffer-overflow vulnerability affecting the application's FTP server. An attacker can exploit this issue to execute arbitrary code within the context of the affected application. Failed exploit attempts will result in a denial-of-service condition.

This issue affects the following:

• IIS 5.0
• IIS 5.1
• IIS 6.0 (denial of service only)
• IIS 7.0 (denial of service only)

Note that Microsoft IIS 7.0 with FTP Service 7.5 is not affected.
