An update of the libarchive package has been released.

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2016:1853 advisory.

    OpenShift Enterprise by Red Hat is the company's cloud computing Platform-     as-a-Service (PaaS) solution designed for on-premise or private cloud     deployments.

    Security Fix(es):

    * When processing an archive file that contains an archive entry with type 1 (hardlink) but also having a     non-zero data size a file overwrite can occur. This would allow an attacker that can pass data to an     application that uses libarchive to unpack it to overwrite arbitrary files with arbitrary data.
    (CVE-2016-5418)

    Red Hat would like to thank Insomnia Security for reporting this issue.

    This update also fixes the following bugs:

    * Previously, pods that had a resource request of 0 and specified limits were classified as BestEffort     when they should have been classified as Burstable. This bug fix ensures that those pods are correctly     classified as Burstable.(BZ#1357475)

    * Future versions of docker will require containerized installations of OpenShift Container Platform to     mount /var/lib/origin with the `rslave` flag. New installations of OpenShift Container Platform 3.2 have     this value set. However, upgrades from 3.1 did not properly set this value. This bug fix ensures that this     flag is now set during upgrades, ensuring that OpenShift Container Platform works properly under future     versions of docker. (BZ#1358197)

    * The PersistentVolumeLabel admission plug-in is now enabled by default. This plug-in labels AWS and GCE     volumes with their zone so the scheduler can limit the nodes for a pod to only those in the same zone as     the persistent volumes being used by the pod. (BZ#1365600)

    * Previously, heapster incorrectly generated error messages indicating that it Failed to find node. This     bug fix corrects that error and ensures that erroneous warnings are generated.(BZ#1366367)

    * The deployment controllers' resync interval can now be configured. The previously hard-coded 2-minute     default is the likely cause of performance regressions when thousands of deploymentconfigs are present in     the system. Increase the resync interval by setting deploymentControllerResyncMinute in     /etc/origin/master/master-config.yaml.(BZ#1366381)

    * Previously, AWS-related environment variables were removed from /etc/sysconfig/atomic-openshift-master     files during an upgrade if these values were not included in the advanced installer's inventory file. This     bug fix ensures that these variables are now preserved during upgrades. (BZ#1370641)

    * Previously, updates to the containerized atomic-openshift-node service were not properly reloaded during     upgrades. This bug fix corrects this error and ensures that the service is reloaded during upgrades.
    (BZ#1371708)

    * Previously the installer did not properly configure an environment for flannel when     openshift_use_flannel was set to `true`. This bug fix corrects those errors and the installer will now     correctly deploy environments using flannel. (BZ#1372026)

Tenable has extracted the preceding description block directly from the Red Hat Enterprise 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.

An update for Red Hat OpenShift Enterprise 3.1 is now available.

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

OpenShift Enterprise by Red Hat is the company's cloud computing Platform-as-a-Service (PaaS) solution designed for on-premise or private cloud deployments.

Security Fix(es) :

* A flaw was found in the way libarchive handled hardlink archive entries of non-zero size. Combined with flaws in libarchive's file system sandboxing, this issue could cause an application using libarchive to overwrite arbitrary files with arbitrary data from the archive. (CVE-2016-5418)

(CVE-2016-4809)

  - An integer overflow flaw, leading to a buffer overflow,     was found in libarchive's construction of ISO9660     volumes. Attempting to create an ISO9660 volume with 2     GB or 4 GB file names could cause the application to     attempt to allocate 20 GB of memory. If this were to     succeed, it could lead to an out of bounds write on the     heap and potential code execution. (CVE-2016-6250)

  - Multiple instances of undefined behavior due to     arithmetic overflow were found in libarchive. Specially     crafted MTREE archives, Compress streams, or ISO9660     volumes could potentially cause the application to fail     to read the archive, or to crash.

According to its self-reported version number, the version of Splunk Enterprise hosted on the remote web server is 5.0.x prior to 5.0.17, 6.0.x prior to 6.0.13, 6.1.x prior to 6.1.12, 6.2.x prior to 6.2.13, 6.3.x prior to 6.3.9, 6.4.x prior to 6.4.5, or 6.5.x prior to 6.5.2;
or else it is Splunk Light prior to 6.5.2. It is, therefore, affected by multiple vulnerabilities :

  - A security bypass vulnerability exists in the libarchive     component due to a failure to properly check hardlinks     that contain payload data. An unauthenticated, remote     attacker can exploit this to bypass sandbox     restrictions. (CVE-2016-5418)

  - An out-of-bounds write error exists in the libarchive     component in the get_line_size() function in     archive_read_support_format_mtree.c that is triggered     when parsing lines. An unauthenticated, remote attacker     can exploit this to crash the library or disclose     memory contents. (CVE-2016-8688)

 -  An information disclosure vulnerability exists in Splunk     Light due to various system information being assigned     to the global window property '$C' when a request is     made to '/en-US/config?autoload=1'. An unauthenticated,     remote attacker attacker can exploit this, via a     specially crafted web page, to disclose sensitive     information. (CVE-2017-5607)

  - A denial of service vulnerability exists in the Splunk     Web component due to improper validation of     user-supplied input. An authenticated, remote attacker     can exploit this, via a specially crafted GET request,     to crash the daemon. (CVE-2017-5880)

  - A flaw exists in the libarchive component in the     check_symlinks() function in archive_write_disk_posix.c     that is triggered during the handling of subdirectories.
    An unauthenticated, remote attacker can exploit this to     overwrite arbitrary files.

  - A flaw exists in the libarchive component in the     edit_deep_directories() function due to symlink checks     and deep-directory support failing to properly handle     overly long pathnames. An unauthenticated, remote     attacker can exploit this to overwrite arbitrary files.

  - A flaw exists in the libarchive component in the     check_symlinks() function that is due to an overly     aggressive cached path handling mechanism. An     unauthenticated, remote attacker can exploit this to     make changes to the permissions of arbitrary     directories.

  - An out-of-bounds write error exists in the libarchive     component in the bsdtar_expand_char() function in util.c     due to improper handling of crafted archives. An     unauthenticated, remote attacker can exploit this, by     convincing a user to open or load a specially crafted     archive, to execute arbitrary code.

  - A stored cross-site scripting (XSS) vulnerability exists     due to improper validation of input before returning it     to users. An authenticated, remote attacker who has     administrative access can exploit this, via a specially     crafted request, to execute arbitrary script code in a     user's browser session.

  - A stored cross-site scripting (XSS) vulnerability exists     in Splunk Light within the web interface due to improper     validation of unspecified input before returning to     users. An authenticated, remote attacker can exploit     this, via a specially crafted request, to execute     arbitrary script code in a user's browser session.

Note that the vulnerabilities in the libarchive component do not affect Splunk Enterprise 6.5.1 or Splunk Light 6.5.1.

* Multiple out-of-bounds read flaws were found in libarchive.
Specially crafted LZA/LZH, AR, MTREE, ZIP, TAR, or RAR files could cause the application to read data out of bounds, potentially disclosing a small amount of application memory, or causing an application crash. (CVE-2015-8919, CVE-2015-8920, CVE-2015-8921, CVE-2015-8923, CVE-2015-8924, CVE-2015-8925, CVE-2015-8926, CVE-2015-8928, CVE-2015-8934)

* Multiple NULL pointer dereference flaws were found in libarchive.

* Multiple infinite loop / resource exhaustion flaws were found in libarchive. Specially crafted GZIP or ISO files could cause the application to consume an excessive amount of resources, eventually leading to a crash on memory exhaustion. (CVE-2016-7166, CVE-2015-8930)

* A denial of service vulnerability was found in libarchive. A specially crafted CPIO archive containing a symbolic link to a large target path could cause memory allocation to fail, causing an application using libarchive that attempted to view or extract such archive to crash. (CVE-2016-4809)

* An integer overflow flaw, leading to a buffer overflow, was found in libarchive's construction of ISO9660 volumes. Attempting to create an ISO9660 volume with 2 GB or 4 GB file names could cause the application to attempt to allocate 20 GB of memory. If this were to succeed, it could lead to an out of bounds write on the heap and potential code execution. (CVE-2016-6250)

* Multiple instances of undefined behavior due to arithmetic overflow were found in libarchive. Specially crafted MTREE archives, Compress streams, or ISO9660 volumes could potentially cause the application to fail to read the archive, or to crash. (CVE-2015-8931, CVE-2015-8932, CVE-2016-5844)
