Synopsis:	Important: autofs security update
Issue date:	2007-12-12
CVE Names:	CVE-2007-5964

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.
