Sun Solaris 10 is prone to a vulnerability that allows remote attackers to bypass authentication. Successfully exploiting this issue allows remote attackers to gain remote access to vulnerable computers. If the targeted computer is configured to allow non-console logins for superusers, then remote superuser access is possible. Update: By exploiting the same underlying flaw, attackers may pass other arguments to the 'login' program, potentially allowing them to bypass other security restrictions. Attackers may potentially bypass the console-only requirement for superuser logins.

Block external access at the network boundary, unless external parties require service.
If global access isn't required, filter access to the affected computer at the network boundary. Restricting access to only trusted computers and networks might greatly reduce the likelihood of remote exploits.
Sun has released an alert along with patches to address this issue. Please see the references for more information.
