Synopsis

A web browser installed on the remote Windows host is affected by multiple vulnerabilities.

Description

The version of Firefox ESR installed on the remote Windows host is prior to 52.1. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2017-12 advisory.

 - Fixed potential buffer overflows in generated Firefox code due to [CVE-2016-6354](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2016-6354) issue in Flex.
 (CVE-2017-5469)

 - A use-after-free vulnerability in SMIL animation functions occurs when pointers to animation elements in an array are dropped from the animation controller while still in use. This results in a potentially exploitable crash. (CVE-2017-5433)

 - A use-after-free vulnerability occurs during transaction processing in the editor during design mode interactions. This results in a potentially exploitable crash. (CVE-2017-5435)

 - An out-of-bounds write in the Graphite 2 library triggered with a maliciously crafted Graphite font. This results in a potentially exploitable crash. This issue was fixed in the Graphite 2 library as well as Mozilla products. (CVE-2017-5436)

 - An out-of-bounds write during Base64 decoding operation in the Network Security Services (NSS) library due to insufficient memory being allocated to the buffer. This results in a potentially exploitable crash. The NSS library has been updated to fix this issue to address this issue and Firefox ESR 52.1 has been updated with NSS version 3.28.4. (CVE-2017-5461)

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

Solution

Upgrade to Mozilla Firefox ESR version 52.1 or later.
