Versions of Mozilla Firefox ESR earlier than 45.5 are unpatched for the following vulnerabilities :

 - An overflow condition exists in the 'RASTERIZE_EDGES()' function in 'gfx/cairo/libpixman/src/pixman-edge-imp.h'. The issue is triggered as certain input is not properly validated when handling SVG content. This may allow a context-dependent attacker to cause a heap-based overflow, potentially allowing the execution of arbitrary code.
 - A flaw exists that is triggered when the Mozilla Updater is run with the updater's log file in the working directory pointing to a hardlink. This may allow a local attacker to append data to an arbitrary local file.
 - A flaw exists in the Mozilla Updater that is triggered as it may select an arbitrary target working directory to output files from the update process. No further details have been provided by the vendor.
 - A flaw exists that is triggered when length checking JavaScript arguments. This may allow a context-dependent attacker to have an unspecified impact.
 - A flaw exists that is triggered as add-on update IDs are not properly validated. This may allow an attacker with the ability to intercept network traffic '(e.g'. MitM, DNS cache poisoning) to provide malicious add-on updates.

 - 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.
