Mozilla Firefox < 57.0.1 Multiple Vulnerabilities

low Nessus Network Monitor Plugin ID 700323
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.


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


Versions of Mozilla Firefox earlier than 57.0.1 are unpatched for the following vulnerabilities :

- A flaw exists in the 'PerDocumentStyleDataImpl::visited_styles_enabled()' function in 'servo/components/style/gecko/'. The issue is triggered when handling the CSS ':visited' selector for a document being used as an SVG image. With a specially crafted web page, a context-dependent attacker disclose visited history information. (CVE-2017-7844)
- A flaw exists in the 'FactoryOp::CheckPermission()' function in 'dom/indexedDB/ActorsParent.cpp' that is triggered as a web worker in Private Browsing mode can write to IndexedDB. With a specially crafted web page, a context-dependent attacker can uniquely fingerprint a user even when browsing in Private Browsing mode. (CVE-2017-7843)


Upgrade to Firefox version 57.0.1 or later.
