 - A flaw exists in 'toolkit/components/extensions/ExtensionContent.jsm' that is triggered as WebExtensions may inappropriately access the mozAddonManager API. This may allow a context-dependent attacker to use a specially crafted extension to install further extensions without a user's permission.
 - A flaw exists in 'dom/canvas/CanvasRenderingContext2D.cpp' that is triggered by the use of the feDisplacementMap filter on images that are loaded cross-origin. This may allow a context-dependent attacker to conduct a timing attack and have an unspecified impact.
 - A flaw exists in the 'nsBaseChannel::Redirect()' function in 'netwerk/base/nsBaseChannel.cpp'. The issue is triggered as local shortcut files may be used to bypass the same-origin policy and load local content from the disk.
 - A flaw exists in the 'ProcessSoftwareUpdateCommand()' function in 'toolkit/components/maintenanceservice/workmonitor.cpp', as it may copy 'updater.exe' from untrusted directories. This may allow a local attacker to read files with SYSTEM privileges.
 - A flaw exists that is triggered when a page load is disrupted. This may result in the previous page's favicon and SSL indicator persisting, potentially misleading a user about the URL of the page being visited.
 - A flaw exists that is triggered when a previously installed application defines the same signature-level permissions as Firefox. This may allow a local attacker to intercept and disclose AuthTokens intended to be sent to Firefox.
 - A flaw exists that is triggered when a previously installed application defines the same signature-level permissions as Firefox. This may allow a local attacker to intercept and disclose API keys intended to be sent to Firefox.
 - A flaw exists in 'mobile/android/base/java/org/mozilla/gecko/PrivateTab.java' that is triggered, as browsing metadata from private browsing may persist in the 'browser.db' and 'browser.db'-wal files within a Firefox profile. This may potentially allow a physically present attacker to disclose information about private browsing.
 - A flaw exists in 'dom/bindings/Codegen.py' that is triggered when loading pages in a sidebar via a bookmark. This may allow the page to reference a privileged chrome window, violating the same-origin policy and engaging in limited JavaScript operations.
 - A flaw exists that is triggered as the 'windows.create' schema doesn't specify "format": "relativeUrl". This may allow a context-dependent attacker to escape the WebExtension sandbox.
 - An unspecified flaw exists in 'divSpoiler' that may allow an attacker to conduct a side-channel attack. No further details have been provided by the vendor.
 - A flaw exists that is triggered as the "select" dropdown menu may potentially cover location bar content, allowing a context-dependent attacker to spoof the location bar.
 - An integer overflow condition exists in the 'XML_Parse()' function in 'parser/expat/lib/xmlparse.c'. The issue is triggered as certain input is not properly validated when parsing XML content. This may allow a context-dependent attacker to have an unspecified impact.
 - A flaw exists in the 'nsCSPHostSrc::permits()' function in 'dom/security/nsCSPUtils.cpp' that is triggered when the Content Security Policy (CSP) is combined with HTTP to HTTPS redirection. This may potentially allow a context-dependent attacker to enumerate the existence of a known site in a user's browser history.
 - 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 'EventListenerManager::GetListenerInfo()' function in 'dom/events/EventListenerManager.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.

The version of Mozilla Firefox installed on the remote Windows host is prior to 50.0. It is, therefore, affected by multiple vulnerabilities, the majority of which are remote code execution vulnerabilities. An unauthenticated, remote attacker can exploit these vulnerabilities by convincing a user to visit a specially crafted website, resulting in the execution of arbitrary code in the context of the current user.

The version of Mozilla Firefox ESR installed on the remote Windows host is 45.x prior to 45.5. It is, therefore, affected by multiple vulnerabilities, the majority of which are remote code execution vulnerabilities. An unauthenticated, remote attacker can exploit these vulnerabilities by convincing a user to visit a specially crafted website, resulting in the execution of arbitrary code in the context of the current user.

The version of Mozilla Firefox installed on the remote macOS or Mac OS X host is prior to 50.0.

The version of Mozilla Firefox ESR installed on the remote macOS or Mac OS X host is 45.x prior to 45.4. It is, therefore, affected by multiple vulnerabilities, the majority of which are remote code execution vulnerabilities. An unauthenticated, remote attacker can exploit these vulnerabilities by convincing a user to visit a specially crafted website, resulting in the execution of arbitrary code in the context of the current user.

Multiple security issues have been found in the Mozilla Firefox web browser: Multiple memory safety errors, buffer overflows and other implementation errors may lead to the execution of arbitrary code or bypass of the same-origin policy. Also, a man-in-the-middle attack in the addon update mechanism has been fixed.
