eSO Security Advisory: 4197
Discovery Date: October 29, 2001 ID: eSO:4197 Title: Sun Solaris cachefsd denial of service 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 and Development Team Technical Contributor: Richard Johnson of the eSecurityOnline Research and Development Team CVE Reference: CAN-2002-0085

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.
