A vulnerability in the way Sun Java System Web Proxy Server processes malformed packets may allow execution of arbitrary code.
SOCKS is a network protocol that provides a framework that allows client-server applications to securely use network firewall services. A vulnerability exists in the way Sun Java System Web Proxy Server handles specially crafted SOCKS packets. According to iDefense Security Advisory 05.25.07:
The problem specifically exists within the "sockd" daemon. This daemon implements SOCKS proxy support for the Web Proxy product. Attackers can cause a buffer overflow by manipulating certain bytes during protocol negotiation.
An unauthenticated attacker on the local network may be able to execute arbitrary code with the privileges of the SOCKS server or cause a denial of service.
