DESCRIPTION:
Steve Kemp has reported two vulnerabilities in GNUMP3d, which can be
exploited by malicious people to conduct cross-site scripting and
directory traversal attacks.

1) Input passed in the URL is not isn't properly sanitised before
being returned to the user in the 404 error page. This can be
exploited to execute arbitrary HTML and script code in a user's
browser session in context of an affected site.

2) An input validation error in the user supplied URL makes it
possible to escape the media file root directory and retrieve files
from the system via directory traversal attacks using
specially-crafted directory traversal character sequences.

Example:
http://[host]/.//../////././/../////./[file]

The vulnerability has been reported in version 2.9.3. Other versions
may also be affected.

SOLUTION:
Update to version 2.9.6.
