an IP spoofing issue.");

"The version of Gallery hosted on the remote web server allows an
attacker to spoof the IP address with a bogus 'X_FORWARDED_FOR' HTTP
header. 

In addition, an authenticated attacker can reportedly leverage this
flaw to launch cross-site scripting attacks by adding comments to a
photo.  The application also reportedly fails to validate a session
id before using it, which can be used to delete arbitrary files on
the remote host subject to the privileges of the web server user id;
however, Nessus has not tested for these additional issues.");
