Description:
Sun Solaris cachefsd is vulnerable to a flaw that allows remote 
attackers to cause a denial of service condition. The problem is due
to the way the program handles RPC requests that contain an invalid
procedure call. An attacker can send a call that will cause cachefsd
to crash.  

Technical Recommendation:
As a workaround solution, ensure RPC services are blocked at the 
firewall. Otherwise, disable cachefsd.
