Scientific Linux Security Update : autofs on SL5.x i386/x86_64

This script is Copyright (C) 2012 Tenable Network Security, Inc.


Synopsis :

The remote Scientific Linux host is missing a security update.

Description :

There was a security issue with the default installed configuration of
autofs version 5 whereby the entry for the 'hosts' map did not specify
the 'nosuid' mount option. A local user with control of a remote nfs
server could create a setuid root executable within an exported
filesystem on the remote nfs server that, if mounted using the default
hosts map, would allow the user to gain root privileges.
(CVE-2007-5964)

NOTICE: Due to the fact that autofs always mounted hosts map entries
suid by default, autofs has now been altered to always use the
'nosuid' option when mounting from the default hosts map. The 'suid'
option must be explicitly given in the master map entry to revert to
the old behavior. This change affects only the hosts map which
corresponds to the /net entry in the default configuration.

Medium / CVSS Base Score : 6.9
