Description Josh Bressers 2005-10-13 13:24:24 EDT

The NTLM authentication code in wget was derived form the libcurl NTLM auth, so
wget is vulnerable to this issue.

This text was scavanged from the libcurl advisory:

libcurl's NTLM function can overflow a stack-based buffer if given a too long
user name or domain name. This would happen if you enable NTLM authentication
and either:

 A - pass in a user name and domain name to libcurl that together are longer
     than 192 bytes

 B - allow (lib)curl to follow HTTP "redirects" (Location: and the appropriate
     HTTP 30x response code) and the new URL contains a URL with a user name
     and domain name that together are longer than 192 bytes
