vulnerability
Impact: Remote attackers can cause a denial of service
condition
Affected Technology: Solaris 2.6, 7, 8 SPARC and x86
Vendor Status: Vendor notified
Discovered By: Kevin Kotas of the eSecurityOnline Research

Advisory Location:
http://www.eSecurityOnline.com/advisories/eSO4197.asp

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.
