A heap based buffer overflow exists in the handling of FTP resources.
Specifically the vulnerability resides within the code responsible for
handling HTTP GET requests.
Exploitation of this issue allows an attacker to execute arbitrary code

send the HTTP GET request to the Sun Java Web Proxy Server and upon
processing the request execution of arbitrary code would be possible.
Sun Java System Web Proxy Server 4.0 through 4.0.7 is vulnerable in the
