The remote host is vulnerable to a heap overflow.
The remote host is running WebMod. WebMod is a web server that is used in popular online games (such as Half-Life). WebMod is the administrative interface to the currently-running game. This version of WebMod is vulnerable to a remote heap overflow. The flaw is in the way that WebMod handles large 'Content-Length' HTTP headers.
Upgrade to version 0.48 or higher.
