Firefox ESR < 38.1.1 PDF Reader Arbitrary File Access (Mac OS X)

medium Nessus Plugin ID 85272
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 Mac OS X host contains a web browser that is affected by an arbitrary file access vulnerability.

Description

The version of Firefox ESR installed on the remote Mac OS X host is prior to 38.1.1. It is, therefore, affected by a vulnerability in the same origin policy in which an attacker can inject script code into a non-privileged part of browser's built-in PDF reader, resulting in gaining access to sensitive local files.

Solution

Upgrade to Firefox ESR 38.1.1 or later.
