Language:

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 52.6. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2018-03 advisory.

 - A use-after-free vulnerability can occur during font face manipulation when a font face is freed while still in use, resulting in a potentially exploitable crash. (CVE-2018-5104)

 - A use-after-free vulnerability can occur during WebRTC connections when interacting with the DTMF timers.
 This results in a potentially exploitable crash. (CVE-2018-5091)

 - An integer overflow vulnerability in the Skia library when allocating memory for edge builders on some systems with at least 8 GB of RAM. This results in the use of uninitialized memory, resulting in a potentially exploitable crash. (CVE-2018-5095)

 - A use-after-free vulnerability can occur while editing events in form elements on a page, resulting in a potentially exploitable crash. (CVE-2018-5096)

 - A use-after-free vulnerability can occur during XSL transformations when the source document for the transformation is manipulated by script content during the transformation. This results in a potentially exploitable crash. (CVE-2018-5097)

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 52.6 or later.
