high Nessus Network Monitor Plugin ID 9751

Synopsis

The remote host has a web browser installed that is vulnerable to multiple attack vectors.

Description

Versions of Mozilla Firefox prior to 49.0.2 are unpatched for the following vulnerabilities :

- An error is triggered during actor destruction with 'service workers'. This may allow a context-dependent attacker to dereference already freed memory and potentially execute arbitrary code. (CVE-2016-5287)
- An unspecified flaw is triggered when e10s is disabled. This may allow a context-dependent attacker to use specially crafted web content to disclose potentially sensitive information in the HTTP cache related to page visits and content. (CVE-2016-5288)

Solution

Upgrade to Firefox version 49.0.2 or later.
