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
Vendor Status: Vendor notified
Discovered By: Kevin Kotas of the eSecurityOnline Research and Development Team
Technical Contributor: Richard Johnson of the eSecurityOnline Research and Development Team
CVE Reference: CAN-2002-0084
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.
As a workaround solution, ensure RPC services are blocked at the firewall. Otherwise, disable cachefsd.
