Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Updated autofs packages that fix one security issue, several bugs, and add one enhancement are now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having Moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

The autofs utility controls the operation of the automount daemon. The daemon automatically mounts file systems when in use and unmounts them when they are not busy.

It was found that program-based automounter maps that used interpreted languages such as Python used standard environment variables to locate and load modules of those languages. A local attacker could potentially use this flaw to escalate their privileges on the system.
(CVE-2014-8169)

Note: This issue has been fixed by adding the 'AUTOFS_' prefix to the affected environment variables so that they are not used to subvert the system. A configuration option ('force_standard_program_map_env') to override this prefix and to use the environment variables without the prefix has been added. In addition, warnings have been added to the manual page and to the installed configuration file. Now, by default the standard variables of the program map are provided only with the prefix added to its name.

Red Hat would like to thank the Georgia Institute of Technology for reporting this issue.

Notably, this update fixes the following bugs :

* When the 'ls *' command was run in the root of an indirect mount, autofs attempted to literally mount the wildcard character (*) causing it to be added to the negative cache. If done before a valid mount, autofs then failed on further mount attempts inside the mount point, valid or not. This has been fixed, and wildcard map entries now function in the described situation. (BZ#1166457)

* When autofs encountered a syntax error consisting of a duplicate entry in a multimap entry, it reported an error and did not mount the map entry. With this update, autofs has been amended to report the problem in the log to alert the system administrator and use the last seen instance of the duplicate entry rather than fail. (BZ#1205600)

* In the ldap and sss lookup modules, the map reading functions did not distinguish between the 'no entry found' and 'service not available' errors. Consequently, when the 'service not available' response was returned from a master map read, autofs did not update the mounts. An 'entry not found' return does not prevent the map update, so the ldap and sss lookup modules were updated to distinguish between these two returns and now work as expected. (BZ#1233065)

In addition, this update adds the following enhancement :

* The description of the configuration parameter map_hash_table_size was missing from the autofs.conf(5) man page and its description in the configuration file comments was insufficient. A description of the parameter has been added to autofs.conf(5), and the configuration file comments have been updated. (BZ#1238573)

All autofs users are advised to upgrade to these updated packages, which contain backported patches to correct these issues and add this enhancement.

The remote MiracleLinux 7 host has a package installed that is affected by a vulnerability as referenced in the AXSA:2015-744:01 advisory.

    autofs is a daemon which automatically mounts filesystems when you use     them, and unmounts them later when you are not using them.  This can     include network filesystems, CD-ROMs, floppies, and so forth.
    Security issues fixed with this release:
    CVE-2014-8169     automount 5.0.8, when a program map uses certain interpreted     languages, uses the calling user's USER and HOME environment variable     values instead of the values for the user used to run the mapped     program, which allows local users to gain privileges via a Trojan     horse program in the user home directory.
    Fixed bugs:
    * When the ls * command was run in the root of an indirect mount, autofs attempted to literally mount     the wildcard character (*) causing it to be added to the negative cache. If done before a valid mount,     autofs then failed on further mount attempts inside the mount point, valid or not. This has been fixed,     and wildcard map entries now function in the described situation.
    * When autofs encountered a syntax error consisting of a duplicate entry in a multimap entry, it reported     an error and did not mount the map entry. With this update, autofs has been amended to report the problem     in the log to alert the system administrator and use the last seen instance of the duplicate entry rather     than fail.

Consequently, when the service not available response was     returned from a master map read, autofs did not update the mounts. An entry not found return does not     prevent the map update, so the ldap and sss lookup modules were updated to distinguish between these two     returns and now work as expected.
    Enhancements:
    * The description of the configuration parameter map_hash_table_size was missing from the autofs.conf(5)     man page and its description in the configuration file comments was insufficient. A description of the     parameter has been added to autofs.conf(5), and the configuration file comments have been updated.
