"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."

"From Red Hat Security Advisory 2015:1344 :

Updated autofs packages that fix one security issue and several bugs
are now available for Red Hat Enterprise Linux 6.

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 would use 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.

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.
(BZ#1163957)

* 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 mounting the last
seen instance of the duplicate entry rather than fail, and to report
the problem in the log files to alert the system administrator.
(BZ#1124083)

* 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. (BZ#1153130)

* 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. (BZ#1156387)

* 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. (BZ#1175671)

* 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. (BZ#1201195)

Users of autofs are advised to upgrade to these updated packages,
which contain backported patches to correct these issues."

"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."

"It was found that program-based automounter maps that used interpreted
languages such as Python would use 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.

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
    mounting the 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."
