Mozilla Firefox < 65.0.1 Multiple Vulnerabilities

high Nessus Network Monitor Plugin ID 700486
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

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

Description

The version of Firefox installed on the remote host is prior to 65.0.1. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2019-04 advisory:

- A use-after-free vulnerability in the Skia library can occur when creating a path, leading to a potentially exploitable crash. (CVE-2018-18356)
- An integer overflow vulnerability in the Skia library can occur after specific transform operations, leading to a potentially exploitable crash. (CVE-2019-5785)
- Cross-origin images can be read from a canvas element in violation of the same-origin policy using the transferFromImageBitmap method. Note: This only affects Firefox 65. Previous versions are unaffected. (CVE-2018-18511)

Note that Nessus Network Monitor has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Mozilla Firefox version 65.0.1 or later.
