Title: Sun Solaris cachefsd mount file buffer
overflow vulnerability
Impact: Local attackers can gain root privileges
Affected Technology: Solaris 2.6, 7, 8 SPARC and x86

Advisory Location:
http://www.eSecurityOnline.com/advisories/eSO4198.asp
Description:
Sun Solaris cachefsd is vulnerable to a flaw that can allow attackers
to execute arbitrary code. The problem is due to insufficient bounds
checking on mounts that are supplied by a user. An attacker can create
a file and have cachefsd process it to gain root privileges.
Technical Recommendation:
As a workaround solution, ensure RPC services are blocked at the
firewall. Otherwise, disable cachefsd.
