sun-java-web-socks-bo (34524) The risk level is classified as HighHigh Risk

Description:

Sun Java System Web Proxy Server is vulnerable to multiple stack-based buffer overflows, caused by improper bounds checking by the SOCKS module. By sending specially-crafted packets to the SOCKS server, a remote attacker could overflow a buffer and execute arbitrary code on the system with root privileges or cause the server to crash.
