Synopsis: Important: autofs security update Issue date: 2007-12-20 CVE Names: CVE-2007-6285 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.
