high Nessus Network Monitor Plugin ID 700329
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

The remote host has a web browser installed that is vulnerable to multiple Remote Code Execution (RCE) attack vectors.

Description

The version of Mozilla Firefox installed on the remote Windows host is prior to 59.0.1. It is, therefore, affected by multiple code execution vulnerabilities. A out-of-bounds write flaw exists in multiple functions of the codebook.c script when decoding Vorbis audio data. A context-dependent attacker could corrupt memory and potentially execute arbitrary code. (CVE-2018-5146, CVE-2018-5147)

Solution

Upgrade to Firefox version 59.0.1 or later.
