Red Hat Security Advisory
Synopsis: Important: autofs security update
Advisory ID: RHSA-2007:1176-01
Advisory URL: https://rhn.redhat.com/errata/RHSA-2007-1176.html
Issue date: 2007-12-20
Updated on: 2007-12-20
Product: Red Hat Enterprise Linux
CVE Names: CVE-2007-6285
- - ---------------------------------------------------------------------
1. Summary:
Updated autofs packages that fix a security issue are now available for Red
Hat Enterprise Linux 5.
This update has been rated as having important security impact by the Red
Hat Security Response Team.
2. Relevant releases/architectures:
Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64
Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64
3. Problem description:
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.
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 autofs 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.
4. Solution:
Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
This update is available via Red Hat Network. Details on how to use
the Red Hat Network to apply this update are available at
