Mozilla Firefox ESR < 60.3 Multiple Vulnerabilities

High Nessus Plugin ID 118395

Synopsis

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

Description

The version of Mozilla Firefox ESR installed on the remote Windows host is prior to 60.3. It is, therefore, affected by multiple vulnerabilities :

- During HTTP Live Stream playback on Firefox for Android, audio data can be accessed across origins in violation of security policies. Because the problem is in the underlying Android service, this issue is addressed by treating all HLS streams as cross-origin and opaque to access. *Note: this issue only affects Firefox for Android. Desktop versions of Firefox are unaffected.* (CVE-2018-12391)

- When manipulating user events in nested loops while opening a document through script, it is possible to trigger a potentially exploitable crash due to poor event handling. (CVE-2018-12392)

- A potential vulnerability was found in 32-bit builds where an integer overflow during the conversion of scripts to an internal UTF-16 representation could result in allocating a buffer too small for the conversion. This leads to a possible out-of-bounds write. *Note: 64-bit builds are not vulnerable to this issue.* (CVE-2018-12393)

- By rewriting the Host request headers using the webRequest API, a WebExtension can bypass domain restrictions through domain fronting. This would allow access to domains that share a host that are otherwise restricted. (CVE-2018-12395)

- A vulnerability where a WebExtension can run content scripts in disallowed contexts following navigation or other events. This allows for potential privilege escalation by the WebExtension on sites where content scripts should not be run. (CVE-2018-12396)

- A WebExtension can request access to local files without the warning prompt stating that the extension will 'Access your data for all websites' being displayed to the user. This allows extensions to run content scripts in local pages without permission warnings when a local file is opened. (CVE-2018-12397)

- Mozilla developers and community members Daniel Veditz and Philipp reported memory safety bugs present in Firefox ESR 60.2. 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-2018-12389)

- Mozilla developers and community members Christian Holler, Bob Owen, Boris Zbarsky, Calixte Denizet, Jason Kratzer, Jed Davis, Taegeon Lee, Philipp, Ronald Crane, Raul Gurzau, Gary Kwong, Tyson Smith, Raymond Forbes, and Bogdan Tara reported memory safety bugs present in Firefox 62 and Firefox ESR 60.2. 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-2018-12390)

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

Solution

Upgrade to Mozilla Firefox ESR version 60.3 or later.
