 Mandriva Linux Security Advisory                       MDVSA-2008:009-1
 http://www.mandriva.com/security/
 _______________________________________________________________________

 Package : autofs
 Date    : January 12, 2008
 Affected: 2007.1, 2008.0
 _______________________________________________________________________

 Problem Description:

 The default behaviour of autofs 5 for the hosts map did not specify the
 nosuid and nodev mount options.  This could allow a local user with
 control of a remote NFS server to create a setuid root executable on
 the exported filesystem of the remote NFS server.  If this filesystem
 was mounted with the default hosts map, it would allow the user to
 obtain root privileges (CVE-2007-5964).  Likewise, the same scenario
 would be available for local users able to create device files on
 the exported filesystem which could allow the user to gain access to
 important system devices (CVE-2007-6285).

 Because the default behaviour of autofs was to mount -hosts map
 entries with the dev and suid options enabled by default, autofs has
 been altered to always use nodev and nosuid by default.  In order
 to have the old behaviour, the configuration must now explicitly set
 the dev and/or suid options.

 This change only affects the -hosts map which corresponds to the /net
 entry in the default configuration.

 Update:

 The previous update shipped with an incorrect LDAP lookup module
 that would prevent the automount daemon from starting.  This update
 corrects that problem.
