"The cachefsd RPC service is running on the remote host. It is,
therefore, potentially affected by the following vulnerabilities :

  - A heap-based buffer overflow condition exists in the
   cfsd_calloc() function that allows an unauthenticated,
   remote attacker to execute arbitrary code via a long
   directory and cache name. (CVE-2002-0033 / ESCROWUPGRADE)

  - A heap-based buffer overflow condition exists in the
   fscache_setup() function that allows a local attacker
   to gain root privileges via a long mount argument.
   (CVE-2002-0084)

ESCROWUPGRADE is one of multiple Equation Group vulnerabilities and
exploits disclosed on 2017/04/08 by a group known as the Shadow
Brokers.

Note that Nessus has not attempted to exploit these issues but has
instead only detected that the service is running.");
