Summary: 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. 2. Relevant releases/architectures: Red Hat Enterprise Linux Client (v. 7) - x86_64 Red Hat Enterprise Linux ComputeNode (v. 7) - x86_64 Red Hat Enterprise Linux Server (v. 7) - aarch64, ppc64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 7) - x86_64 3. Description: 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 environmentvariables 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 beenadded 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. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. For details on how to apply this update, refer to: https://access.redhat.com/articles/11258 5. Bugs fixed (https://bugzilla.redhat.com/): 1161474 - automount segment fault in parse_sun.so for negative parser tests 1166457 - Autofs unable to mount indirect after attempt to mount wildcard 1192565 - CVE-2014-8169 autofs: priv escalation via interpreter load path for program based automount maps 1201582 - autofs: MAPFMT_DEFAULT is not macro in lookup_program.c 1218045 - Similar but unrelated NFS exports block proper mounting of "parent" mount point 1233067 - autofs is performing excessive direct mount map re-reads 1233069 - Direct map does not expire if map is initially empty 1263508 - Heavy program map usage can lead to a hang 6.

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. Bug fixes: * If the "ls *" command was executed before a valid mount, the autofs program failed on further mount attempts inside the mount point, whether the mount point was valid or not. While attempting to mount, the "ls *" command of the root directory of an indirect mount was executed, which led to an attempt to mount "*", causing it to be added to the negative map entry cache. This bug has been fixed by checking for and not adding "*" while updating the negative map entry cache. * The autofs program by design did not mount host map entries that were duplicate exports in an NFS server export list. The duplicate entries in a multi-mount map entry were recognized as a syntax error and autofs refused to perform mounts when the duplicate entries occurred. Now, autofs has been changed to continue mountingthe last seen instance of the duplicate entry rather than fail, and to report the problem in the log files to alert the system administrator. * The autofs program did not recognize the yp map type in the master map. This was caused by another change in the master map parser to fix a problem with detecting the map format associated with mapping the type in the master map. The change led to an incorrect length for the type comparison of yp maps that resulted in a match operation failure. This bug has been fixed by correcting the length which is used for the comparison. * The autofs program did not update the export list of the Sun-format maps of the network shares exported from an NFS server. This happened due to a change of the Sun-format map parser leading to the hosts map update to stop working on the map re-read operation. The bug has been now fixed by selectively preventing this type of update only for the Sun-formatted maps. The updates of the export list on the Sun-format maps are now visible and refreshing of the export list is no longer supported for the Sun-formatted hosts map. * Within changes made for adding of the Sun-format maps, an incorrect check was added that caused a segmentation fault in the Sun-format map parser in certain circumstances. This has been now fixed by analyzing the intent of the incorrect check and changing it in order to properly identify the conditions without causing a fault. * A bug in the autofs program map lookup module caused an incorrect map format type comparison. The incorrect comparison affected the Sun-format program maps where it led to the unused macro definitions. The bug in the comparison has been fixed so that the macro definitions are not present for the Sun-format program maps. -- SL6 x86_64 autofs-5.0.5-113.el6.x86_64.rpm autofs-debuginfo-5.0.5-113.el6.x86_64.rpm i386 autofs-5.0.5-113.el6.i686.rpm autofs-debuginfo-5.0.5-113.el6.i686.rpm - Scientific Linux Development Team .

autofs could be made to run programs as an administrator if program maps were configured.. =========================================================================Ubuntu Security Notice USN-2579-1 April 27, 2015 autofs vulnerability ========================================================================= A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 14.10 Summary: autofs could be made to run programs as an administrator if program maps were configured. Software Description: - autofs: kernel-based automounter for Linux Details: It was discovered that autofs incorrectly filtered environment variables when using program maps. When program maps were configured, a local user could use this issue to escalate privileges. This update changes the default behaviour by adding a prefix to environment variables. Sites using program maps will need to adapt to the new variable names, or revert to the previous names by using a new configuration option called FORCE_STANDARD_PROGRAM_MAP_ENV. Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 14.10: autofs 5.0.8-1ubuntu1.1 After a standard system update you need to reboot your computer to make all the necessary changes.

When using autofs with LDAP, a local user could use this flaw to crash autofs, preventing future mount requests from being processed until the autofs service was restarted. Note: This flaw did not impact existing mounts (except for preventing mount expiration). (CVE-2012-2697) This update also fixes the following bugs: * The autofs init script sometimes timed out waiting for the automount daemon to exit and returned a shutdown failure if the daemon failed to exit in time. To resolve this problem, the amount of time that the init script waits for the daemon has been increased to allow for cases where servers are slow to respond or there are many active mounts. * Due to an omission when backporting a change, autofs attempted to download the entire LDAP map at startup. This mistake has now been corrected. * A function to check the validity of a mount location was meant to check only for a small subset of map location errors. A recent modification in error reporting inverted a logic test in this validating function. Consequently, the scope of the test was widened, which caused the automount daemon to report false positive failures. With this update, the faulty logic test has been corrected and false positive failures no longer occur. * When there were many attempts to access invalid or non-existent keys, the automount daemon used excessive CPU resources. As a consequence, systems sometimes became unresponsive. The code has been improved so that automount checks for invalid keys earlier in the process which has eliminateda significant amount of the processing overhead. * The auto.master(5) man page did not document the "-t, --timeout" option in the FORMAT options section.

Description: The autofs utility controls the operation of the automount daemon. The automount daemon automatically mounts and unmounts file systems. A bug fix included in RHBA-2012:0264 introduced a denial of service flaw in autofs. When using autofs with LDAP, a local user could use this flaw to crash autofs, preventing future mount requests from being processed until the autofs service was restarted. Note: This flaw did not impact existing mounts (except for preventing mount expiration). (CVE-2012-2697) Red Hat would like to thank Ray Rocker for reporting this issue. This update also fixes the following bugs: * The autofs init scriptsometimes timed out waiting for the automount daemon to exit and returned a shutdown failure if the daemon failed to exit in time. To resolve this problem, the amount of time that the init script waits for the daemon has been increased to allow for cases where serversare slow to respond or there are many active mounts.

Summary: Updated autofs5 technology preview packages that fix a security issue are now available for Red Hat Enterprise Linux 4. 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 AS version 4 - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Enterprise Linux Desktop version 4 - i386, x86_64 Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64 Red Hat Enterprise Linux WS version 4 - i386, ia64, 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. 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 NFSserver 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. 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.
