Mozilla Firefox ESR < 52.2

critical Nessus Plugin ID 275678

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 52.2. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2017-16 advisory.

 - A number of security vulnerabilities in the Graphite 2 library including out-of-bounds reads, buffer overflow reads and writes, and the use of uninitialized memory. These issues were addressed in Graphite 2 version 1.3.10. (CVE-2017-7778)

 - A use-after-free vulnerability with the frameloader during tree reconstruction while regenerating CSS layout when attempting to use a node in the tree that no longer exists. This results in a potentially exploitable crash. (CVE-2017-5472)

 - A use-after-free vulnerability when using an incorrect URL during the reloading of a docshell. This results in a potentially exploitable crash. (CVE-2017-7749)

 - A use-after-free vulnerability during video control operations when a <code><track></code> element holds a reference to an older window if that window has been replaced in the DOM. This results in a potentially exploitable crash. (CVE-2017-7750)

 - A use-after-free vulnerability with content viewer listeners that results in a potentially exploitable crash. (CVE-2017-7751)

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 52.2 or later.
