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/data.rs’. 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)
