Sun Java Runtime Environment proxy security bypass

sun-jre-proxy-security-bypass (52338) The risk level is classified as MediumMedium Risk

Description:

Sun Java Runtime Environment (JRE) could allow a remote attacker to bypass security restrictions, caused by an error in the proxy mechanism implementation. By persuading a victim to launch an untrusted applet or Java Web Start application, an attacker could exploit this vulnerability to establish a non-authorized socket or URL connection to restricted hosts.
