Solaris cachefsd Multiple Vulnerabilities (ESCROWUPGRADE)

This script is Copyright (C) 2002-2017 Tenable Network Security, Inc.


Synopsis :

The remote RPC service is potentially affected by multiple
vulnerabilities.

Description :

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.

Solution :

Apply the appropriate patch referenced in the vendor's advisory.

Alternatively, disable cachefsd by commenting out cachefsd in
/etc/inetd.conf and then killing the process.
