A Security Vulnerability in IP Multicast Filter processing of Sockets may lead to a system panic or possible execution of Arbitrary Code

1. Impact

A security vulnerability in the Solaris 10 IP (see ip(7P)) kernel module relating to setting a socket's multicast filter may allow a local unprivileged user the ability to panic the system or execute arbitrary commands with all privileges. The ability to panic a system is a type of Denial of Service (DoS).
