Título:	RedHat Security Advisory RHSA-2007:1177
Resumen:	NOSUMMARY
Descripción:	Description: The remote host is missing updates announced in advisory RHSA-2007:1177. 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 -hosts map did not specify the nodev 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 -hosts 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 nosuid mount option in autofs. Both the nodev and nosuid options should be enabled to prevent a possible compromise of machine integrity. Due to the fact that autofs always mounted -hosts map entries dev by default, autofs has now been altered to always use the nodev option when mounting from the default -hosts map. The dev 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. 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. Solution: Please note that this update is available via Red Hat Network.
