"The remote host is running a version of FreeBSD which contains a flaw in the 
'fetch' utility.

'fetch' is a command-line tool used to retrieve data at a given URL. It is used
(among others) by the FreeBSD port collection.

There is an integer overflow condition in the processing of HTTP headers
which may result in a buffer overflow.

An attacker may exploit this flaw to execute arbitrary commands on the remote
host. To exploit this flaw, an attacker would need to lure a victim on the remote
host into downloading a URL from a malicious web server using this utility." );
