cachefsd overflow |
||
Checks the presence of a RPC service Detailed Explanation for this Vulnerability Assessment The cachefsd RPC service is running on this port. Multiple vulnerabilities exist in this service. At least one heap overflow vulnerability can be exploited remotely to obtain root rights by sending a long directory and cache name request to the service. A buffer overflow can result in root rights from local users exploiting the fscache_setup function with a long mount argument. Solaris 2.5.1, 2.6, 7 and 8 are vulnerable to this issue. Sun patch 110896-02 is available for Solaris 8. Other operating systems might be affected as well. *** Nessus did not check for this vulnerability, *** so this might be a false positive Solution : Deactivate this service - there is no patch at this time for pre-8 systems /etc/init.d/cachefs.daemon stop AND: Edit /etc/inetd.conf and disable the 100235/rcp service: #100235/1 tli rpc/tcp wait root /usr/lib/fs/cachefsd cachefsd Then kill -HUP the inetd process id. These activities may need to be repeated after every patch installation.
