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.
