Mozilla Firefox ESR < 45.6 Multiple Vulnerabilities

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 flaw exists that is triggered as certain input is not properly validated when handling HTML5 content. With a specially crafted web page, a context-dependent attacker can corrupt memory and potentially execute arbitrary code.
• An unspecified flaw exists in the ‘nsDocShell::RestoreFromHistory()’ function in ‘docshell/base/nsDocShell.cpp’. This may allow a context-dependent attacker to corrupt memory and potentially execute arbitrary code.
• An unspecified flaw exists in the ‘Factory::CreateDrawTargetForData()’ function in ‘gfx/2d/Factory.cpp’. This may allow a context-dependent attacker to corrupt memory and potentially execute arbitrary code.
• A flaw exists in ‘dom/media/MediaRecorder.cpp’ that is triggered when handling a document’s activity state changes. This may allow a context-dependent attacker to corrupt memory and potentially execute arbitrary code.
• A flaw exists in the ‘nsHttpChunkedDecoder::ParseChunkRemaining()’ function in ‘netwerk/protocol/http/nsHttpChunkedDecoder.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 that is triggered when handling media content. This may allow a context-dependent attacker to dereference already freed memory and potentially execute arbitrary code.
• A flaw exists in the ‘nsDocument::EnumerateSubDocuments()’ function in ‘dom/base/nsDocument.cpp’ that is triggered when adding and removing sub-documents. With a specially crafted web page, a context-dependent attacker can corrupt memory and potentially execute arbitrary code.
• A flaw exists in ‘dom/bindings/BindingUtils.h’ 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 ‘editor/libeditor/HTMLEditor.cpp’ that is triggered when handling DOM subtrees. With a specially crafted web page, a context-dependent attacker can dereference already freed memory and potentially execute arbitrary code.
• A flaw exists in the ‘VaryingPacking::packVarying()’ function in ‘libANGLE/renderer/d3d/hlsl/VaryingPacking.cpp’. This may allow a context-dependent attacker to corrupt memory and crash a process linked against the library or 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.
