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

medium Nessus Plugin ID 60330

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.

Solution

Update the affected autofs package.
