Security Alert for a vulnerability in Solaris 10 IPv6

Sun issued an Security Altert for Solaris 10: A Security Vulnerability in Solaris IPv6 Implementation (ip6(7p)) May Cause a System Panic:

An insufficient validation security vulnerability in the Solaris IPv6 implementation (ip6(7p)) may allow a remote privileged user to panic the system using a crafted packet. This is a type of Denial of Service (DoS).

A workaround and an Interim Security Relief patch are available. There are two possible workarounds: Switching off IPv6 by ifconfig -a6 down or inserting block in quick all with short in your IPFilter configuration.
