Versions of Mozilla Firefox ESR earlier than 45.6 are unpatched for the following vulnerabilities :

 - A flaw exists in the 'GetNPObjectWrapper()' function in 'dom/plugins/base/nsJSNPRuntime.cpp' that is triggered as certain input is not properly validated. This may allow a context-dependent attacker to corrupt memory and potentially execute arbitrary code.
 - An unspecified flaw exists that is triggered as certain input is not properly validated. This may allow a context-dependent attacker to corrupt memory and potentially execute arbitrary code.
 - A flaw exists in the 'ObjectGroup::defaultNewGroup()' function in 'js/src/vm/ObjectGroup.cpp' that is triggered as certain input is not properly validated. This may allow a context-dependent attacker to corrupt memory and potentially execute arbitrary code.

 - A use-after-free error exists in the 'nsNodeUtils::CloneAndAdopt()' function in 'dom/base/nsNodeUtils.cpp' that is triggered when handling failing node adoption. With a specially crafted web page, a context-dependent attacker can dereference already freed memory and potentially execute arbitrary code.
 - A flaw exists that is triggered as event handlers for marquee elements are executed despite restrictions against inline JavaScript. This may allow a context-dependent attacker to bypass the Content Security Policy (CSP).
 - A flaw exists in the 'nsDataDocumentContentPolicy::ShouldLoad()' function in 'dom/base/nsDataDocumentContentPolicy.cpp', as external resources may be inappropriately loaded by SVG images by utilizing 'data: URLs'. This may allow a context-dependent attacker to disclose potentially sensitive cross-domain information.
 - A flaw exists that is triggered as HTML tags from the Pocket server are not properly sanitized before use. This may allow a context-dependent attacker to inject content and gain access to the Pocket Messaging API.
 - A flaw exists in 'browser/extensions/pocket/content/main.js' related to the Pocket toolbar button, as it fails to properly verify the origin of events. This may potentially allow a context-dependent attacker to execute commands from other contexts.
 - A flaw exists that is triggered as atom information may be exposed. This may allow a context-dependent attacker to use a JavaScript Map/Set timing attack to determine if atoms are used by other compartments or zones, potentially disclosing cross-domain information.

Versions of Mozilla Firefox prior to 50.1 are unpatched for the following vulnerabilities :

This flaw exists because 'addon-sdk/source/lib/sdk/ui/frame/view.html' and 'addon-sdk/source/lib/sdk/ui/frame/view.js' within the Add-ons SDK do not properly validate input before returning it to users. This may allow a context-dependent attacker to create a specially crafted request that would execute arbitrary script code in a user's browser session within the trust relationship between their browser and an add-on.
