The version of Mozilla Firefox ESR installed on the remote Windows host is 45.x prior to 45.6. It is, therefore, affected by the following vulnerabilities :
Multiple memory corruption issues exist, such as when handling document state changes or HTML5 content, or else due to dereferencing already freed memory or improper validation of user-supplied input. An unauthenticated, remote attacker can exploit these to cause a denial of service condition or the execution of arbitrary code. (CVE-2016-9893)
A security bypass vulnerability exists due to event handlers for marquee elements being executed despite a Content Security Policy (CSP) that disallowed inline JavaScript. An unauthenticated, remote attacker can exploit this to impact integrity. (CVE-2016-9895)
A memory corruption issue exists in libGLES when WebGL functions use a vector constructor with a varying array within libGLES. An unauthenticated, remote attacker can exploit this to cause a denial of service condition or the execution of arbitrary code. (CVE-2016-9897)
A use-after-free error exists in Editor, specifically within file editor/libeditor/HTMLEditor.cpp, when handling DOM subtrees. An unauthenticated, remote attacker can exploit this to cause a denial of service condition or the execution of arbitrary code.
(CVE-2016-9898)
A use-after-free error exists in the nsNodeUtils::CloneAndAdopt() function within file dom/base/nsNodeUtils.cpp, while manipulating DOM events and removing audio elements, due to improper handling of failing node adoption. An unauthenticated, remote attacker can exploit this to cause a denial of service condition or the execution of arbitrary code.
(CVE-2016-9899)
A security bypass vulnerability exists in the nsDataDocumentContentPolicy::ShouldLoad() function within file dom/base/nsDataDocumentContentPolicy.cpp that allows external resources to be inappropriately loaded by SVG images by utilizing βdata:β URLs. An unauthenticated, remote attacker can exploit this to disclose sensitive cross-domain information.
(CVE-2016-9900)
A flaw exists due to improper sanitization of HTML tags received from the Pocket server. An unauthenticated, remote attacker can exploit this to run JavaScript code in the about:pocket-saved (unprivileged) page, giving it access to Pocketβs messaging API through HTML injection.
(CVE-2016-9901)
A flaw exists in the Pocket toolbar button, specifically in browser/extensions/pocket/content/main.js, due to improper verification of the origin of events fired from its own pages. An unauthenticated, remote attacker can exploit this to inject content and commands from other origins into the Pocket context. Note that this issue does not affect users with e10s enabled. (CVE-2016-9902)
An information disclosure vulnerability exists that allows an unauthenticated, remote attacker to determine whether an atom is used by another compartment or zone in specific contexts, by utilizing a JavaScript Map/Set timing attack. (CVE-2016-9904)
A memory corruption issue exists in the nsDocument::EnumerateSubDocuments() function within file dom/base/nsDocument.cpp when adding and removing sub-documents. An unauthenticated, remote attacker can exploit this, via a specially crafted web page, to cause a denial of service condition or the execution of arbitrary code. (CVE-2016-9905)
