Title: Microsoft Windows Shortcut Vulnerability

Severity: MODERATE

Description:

The Windows API that handles shortcut navigation is susceptible to buffer overflow attacks. The API, "SHGetPathFromIDList" will parse a shortcut file (.lnk) to find the target file, directory or URL. A specifically malformed link will cause any program using the API to follow that shortcut to crash.

NOTE: While this vulnerability listing, as well as the exploit and the original USSR advisory only mention Serv-U FTP server, any Windows, Microsoft, or 3rd party program that uses the API could be vulnerable to this.
