This update upgrades Firefox to version 52.0 ESR.

Security Fix(es) :

  - Multiple flaws were found in the processing of malformed     web content. A web page containing malicious content     could cause Firefox to crash or, potentially, execute     arbitrary code with the privileges of the user running     Firefox. (CVE-2017-5398, CVE-2017-5400, CVE-2017-5401,     CVE-2017-5402, CVE-2017-5404, CVE-2017-5407,     CVE-2017-5408, CVE-2017-5410, CVE-2017-5405)

The version of Firefox ESR installed on the remote Windows host is prior to 45.8. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2017-06 advisory.

  - Mozilla developers and community members Boris Zbarsky, Christian Holler, Honza Bambas, Jon Coppeard,     Randell Jesup, Andr Bargull, Kan-Ru Chen, and Nathan Froyd reported memory safety bugs present in     Firefox 51 and Firefox ESR 45.7. Some of these bugs showed evidence of memory corruption and we presume     that with enough effort that some of these could be exploited to run arbitrary code. (CVE-2017-5398)

  - Memory corruption resulting in a potentially exploitable crash during garbage collection of JavaScript due     errors in how incremental sweeping is managed for memory cleanup. (CVE-2017-5410)

  - JIT-spray targeting asm.js combined with a heap spray allows for a bypass of ASLR and DEP protections     leading to potential memory corruption attacks. (CVE-2017-5400)

  - A crash triggerable by web content in which an <code>ErrorResult</code> references unassigned memory due     to a logic error. The resulting crash may be exploitable. (CVE-2017-5401)

  - A use-after-free can occur when events are fired for a <code>FontFace</code> object after the object has     been already been destroyed while working with fonts. This results in a potentially exploitable crash.
    (CVE-2017-5402)

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

The version of Thunderbird installed on the remote Windows host is prior to 45.8. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2017-07 advisory.

  - Mozilla developers and community members Boris Zbarsky, Christian Holler, Honza Bambas, Jon Coppeard,     Randell Jesup, Andr Bargull, Kan-Ru Chen, and Nathan Froyd reported memory safety bugs present in     Thunderbird 45.7. Some of these bugs showed evidence of memory corruption and we presume that with enough     effort that some of these could be exploited to run arbitrary code. (CVE-2017-5398)

The version of Firefox installed on the remote Windows host is prior to 52.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2017-05 advisory.

  - Mozilla developers and community members Carsten Book, Calixte Denizet, Christian Holler, Andrew     McCreight, David Bolter, David Keeler, Jon Coppeard, Tyson Smith, Ronald Crane, Tooru Fujisawa, Ben Kelly,     Bob Owen, Jed Davis, Julian Seward, Julian Hector, Philipp, Markus Stange, and  Andr Bargull reported     memory safety bugs present in Firefox 51. Some of these bugs showed evidence of memory corruption and we     presume that with enough effort that some of these could be exploited to run arbitrary code.
    (CVE-2017-5399)

  - A segmentation fault can occur during some bidirectional layout operations. (CVE-2017-5413)

  - JIT-spray targeting asm.js combined with a heap spray allows for a bypass of ASLR and DEP protections     leading to potential memory corruption attacks. (CVE-2017-5400)

  - A crash triggerable by web content in which an <code>ErrorResult</code> references unassigned memory due     to a logic error. The resulting crash may be exploitable. (CVE-2017-5401)

  - A use-after-free can occur when events are fired for a <code>FontFace</code> object after the object has     been already been destroyed while working with fonts. This results in a potentially exploitable crash.

Multiple security issues have been found in the Mozilla Firefox web browser: Multiple memory safety errors, use-after-frees and other implementation errors may lead to the execution of arbitrary code, ASLR bypass, information disclosure or denial of service.

The remote Oracle Linux 5 / 6 / 7 host has a package installed that is affected by multiple vulnerabilities as referenced in the ELSA-2017-0498 advisory.

    [45.8.0-1.0.1]
    - Replaced thunderbird-redhat-default-prefs.js with thunderbird-oracle-default-prefs.js

    [45.8.0-1]
    - Update to 45.8.0

The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3233-1 advisory.

    Multiple security issues were discovered in Thunderbird. If a user were tricked in to opening a specially     crafted website in a browsing context, an attacker could potentially exploit these to bypass same origin     restrictions, obtain sensitive information, cause a denial of service via application crash or hang, or     execute arbitrary code. (CVE-2017-5398, CVE-2017-5400, CVE-2017-5401, CVE-2017-5402, CVE-2017-5404,     CVE-2017-5405, CVE-2017-5407, CVE-2017-5408, CVE-2017-5410)
