CentOS Update for autofs5 CESA-2007:1177 centos4 x86_64

Check for the Version of autofs5

The autofs utility controls the operation of the automount daemon, which automatically mounts file systems when you use them, and unmounts them when you are not using them. This can include network file systems and CD-ROMs. The autofs5 packages were made available as a technology preview in Red Hat Enterprise Linux 4.6. There was a security issue with the default configuration of autofs version 5, whereby the entry for the &quot -hosts&quot map did not specify the &quot nodev&quot mount option. A local user with control of a remote NFS server could create special device files on the remote file system, that if mounted using the default &quot -hosts&quot map, could allow the user to access important system devices. (CVE-2007-6285) This issue is similar to CVE-2007-5964, which fixed a missing &quot nosuid&quot mount option in autofs. Both the &quot nodev&quot and &quot nosuid&quot options should be enabled to prevent a possible compromise of machine integrity. Due to the fact that autofs always mounted &quot -hosts&quot map entries &quot dev&quot by default, autofs has now been altered to always use the &quot nodev&quot option when mounting from the default &quot -hosts&quot map. The &quot dev&quot option must be explicitly given in the master map entry to revert to the old behavior. This change affects only the &quot -hosts&quot map which corresponds to the &quot /net&quot entry in the default configuration. All autofs5 users are advised to upgrade to these updated packages, which resolve this issue. Red Hat would like to thank Tim Baum for reporting this issue.
