The remote host is affected by the vulnerability described in GLSA-202202-03 (Mozilla Firefox: Multiple vulnerabilities)

  - A malicious webpage could have triggered a use-after-free, memory corruption, and a potentially     exploitable crash. *This bug could only be triggered when accessibility was enabled.*. This vulnerability     affects Thunderbird < 78.12, Firefox ESR < 78.12, and Firefox < 90. (CVE-2021-29970)

  - A use-after-free vulnerability was found via testing, and traced to an out-of-date Cairo library. Updating     the library resolved the issue, and may have remediated other, unknown security vulnerabilities as well.
    This vulnerability affects Firefox < 90. (CVE-2021-29972)

  - When network partitioning was enabled, e.g. as a result of Enhanced Tracking Protection settings, a TLS     error page would allow the user to override an error on a domain which had specified HTTP Strict Transport     Security (which implies that the error should not be override-able.) This issue did not affect the network     connections, and they were correctly upgraded to HTTPS automatically. This vulnerability affects Firefox <     90. (CVE-2021-29974)

  - Through a series of DOM manipulations, a message, over which the attacker had control of the text but not     HTML or formatting, could be overlaid on top of another domain (with the new domain correctly shown in the     address bar) resulting in possible user confusion. This vulnerability affects Firefox < 90.
    (CVE-2021-29975)

  - Mozilla developers reported memory safety bugs present in code shared between Firefox and Thunderbird.
    Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of     these could have been exploited to run arbitrary code. This vulnerability affects Thunderbird < 78.12,     Firefox ESR < 78.12, and Firefox < 90. (CVE-2021-29976)

  - Mozilla developers reported memory safety bugs present in Firefox 89. Some of these bugs showed evidence     of memory corruption and we presume that with enough effort some of these could have been exploited to run     arbitrary code. This vulnerability affects Firefox < 90. (CVE-2021-29977)

    (CVE-2021-29986)

  - After requesting multiple permissions, and closing the first permission panel, subsequent permission     panels will be displayed in a different position but still record a click in the default location, making     it possible to trick a user into accepting a permission they did not want to. *This bug only affects     Firefox on Linux. Other operating systems are unaffected.*. This vulnerability affects Firefox < 91 and     Thunderbird < 91. (CVE-2021-29987)

  - Firefox incorrectly treated an inline list-item element as a block element, resulting in an out of bounds     read or memory corruption, and a potentially exploitable crash. This vulnerability affects Thunderbird <     78.13, Thunderbird < 91, Firefox ESR < 78.13, and Firefox < 91. (CVE-2021-29988)

  - Mozilla developers reported memory safety bugs present in Firefox 90 and Firefox ESR 78.12.

This vulnerability affects Firefox < 91. (CVE-2021-29990)

  - Out of bounds write in ANGLE in Google Chrome prior to 91.0.4472.101 allowed a remote attacker to     potentially perform out of bounds memory access via a crafted HTML page. (CVE-2021-30547)

  - Mixed-content checks were unable to analyze opaque origins which led to some mixed content being loaded.
    This vulnerability affects Firefox < 92. (CVE-2021-38491)

  - Mozilla developers reported memory safety bugs present in Firefox 91 and Firefox ESR 78.13. Some of these     bugs showed evidence of memory corruption and we presume that with enough effort some of these could have     been exploited to run arbitrary code. This vulnerability affects Firefox ESR < 78.14, Thunderbird < 78.14,     and Firefox < 92. (CVE-2021-38493)

  - Mozilla developers reported memory safety bugs present in Thunderbird 78.13.0. Some of these bugs showed     evidence of memory corruption and we presume that with enough effort some of these could have been     exploited to run arbitrary code. This vulnerability affects Thunderbird < 91.1 and Firefox ESR < 91.1.
    (CVE-2021-38495)

  - The iframe sandbox rules were not correctly applied to XSLT stylesheets, allowing an iframe to bypass     restrictions such as executing scripts or navigating the top-level frame. This vulnerability affects     Firefox < 94, Thunderbird < 91.3, and Firefox ESR < 91.3. (CVE-2021-38503)

  - When interacting with an HTML input element's file picker dialog with webkitdirectory set, a use-after-     free could have resulted, leading to memory corruption and a potentially exploitable crash. This     vulnerability affects Firefox < 94, Thunderbird < 91.3, and Firefox ESR < 91.3. (CVE-2021-38504)

  - Through a series of navigations, Firefox could have entered fullscreen mode without notification or     warning to the user. This could lead to spoofing attacks on the browser UI including phishing. This     vulnerability affects Firefox < 94, Thunderbird < 91.3, and Firefox ESR < 91.3. (CVE-2021-38506)

  - The Opportunistic Encryption feature of HTTP2 (RFC 8164) allows a connection to be transparently upgraded     to TLS while retaining the visual properties of an HTTP connection, including being same-origin with     unencrypted connections on port 80. However, if a second encrypted port on the same IP address (e.g. port     8443) did not opt-in to opportunistic encryption; a network attacker could forward a connection from the     browser to port 443 to port 8443, causing the browser to treat the content of port 8443 as same-origin     with HTTP. This was resolved by disabling the Opportunistic Encryption feature, which had low usage. This     vulnerability affects Firefox < 94, Thunderbird < 91.3, and Firefox ESR < 91.3. (CVE-2021-38507)

  - By displaying a form validity message in the correct location at the same time as a permission prompt     (such as for geolocation), the validity message could have obscured the prompt, resulting in the user     potentially being tricked into granting the permission. This vulnerability affects Firefox < 94,     Thunderbird < 91.3, and Firefox ESR < 91.3. (CVE-2021-38508)

  - Due to an unusual sequence of attacker-controlled events, a Javascript alert() dialog with arbitrary     (although unstyled) contents could be displayed over top an uncontrolled webpage of the attacker's     choosing. This vulnerability affects Firefox < 94, Thunderbird < 91.3, and Firefox ESR < 91.3.
    (CVE-2021-38509)

  - By misusing a race in our notification code, an attacker could have forcefully hidden the notification for     pages that had received full screen and pointer lock access, which could have been used for spoofing     attacks. This vulnerability affects Thunderbird < 91.4.0, Firefox ESR < 91.4.0, and Firefox < 95.
    (CVE-2021-43538)

  - Failure to correctly record the location of live pointers across wasm instance calls resulted in a GC     occurring within the call not tracing those live pointers. This could have led to a use-after-free causing     a potentially exploitable crash. This vulnerability affects Thunderbird < 91.4.0, Firefox ESR < 91.4.0,     and Firefox < 95. (CVE-2021-43539)

  - WebExtensions with the correct permissions were able to create and install ServiceWorkers for third-party     websites that would not have been uninstalled with the extension. This vulnerability affects Firefox < 95.
    (CVE-2021-43540)

    * Fixed: Fixed an issue which caused tabs from private windows       to be visible in non-private windows when viewing switch-to-       tab results in the address bar panel (bug 1720369)
    * Fixed: Various stability fixes
    * Fixed: Security fix MFSA 2021-37 (bsc#1189547)
    * CVE-2021-29991 (bmo#1724896)       Header Splitting possible with HTTP/3 Responses

    Firefox Extended Support Release 91.0 ESR

    * New: Some of the highlights of the new Extended Support Release are:

      - A number of user interface changes. For more information,         see the Firefox 89 release notes.
      - Firefox now supports logging into Microsoft, work, and         school accounts using Windows single sign-on. Learn more
      - On Windows, updates can now be applied in the background         while Firefox is not running.
      - Firefox for Windows now offers a new page about:third-party         to help identify compatibility issues caused by third-party         applications
      - Version 2 of Firefox's SmartBlock feature further improves         private browsing. Third party Facebook scripts are blocked to         prevent you from being tracked, but are now automatically         loaded 'just in time' if you decide to 'Log in with Facebook'         on any website.
      - Enhanced the privacy of the Firefox Browser's Private         Browsing mode with Total Cookie Protection, which confines         cookies to the site where they were created, preventing         companis from using cookies to track your browsing across         sites. This feature was originally launched in Firefox's ETP         Strict mode.
      - PDF forms now support JavaScript embedded in PDF files.
        Some PDF forms use JavaScript for validation and other         interactive features.
      - You'll encounter less website breakage in Private Browsing         and Strict Enhanced Tracking Protection with SmartBlock,         which provides stand-in scripts so that websites load         properly.
      - Improved Print functionality with a cleaner design and         better integration with your computer's printer settings.
      - Firefox now protects you from supercookies, a type of         tracker that can stay hidden in your browser and track you         online, even after you clear cookies. By isolating         supercookies, Firefox prevents them from tracking your web         browsing from one site to the next.
      - Firefox now remembers your preferred location for saved         bookmarks, displays the bookmarks toolbar by default on new         tabs, and gives you easy access to all of your bookmarks via         a toolbar folder.
      - Native support for macOS devices built with Apple Silicon         CPUs brings dramatic performance improvements over the non-         native build that was shipped in Firefox 83: Firefox launches         over 2.5 times faster and web apps are now twice as         responsive (per the SpeedoMeter 2.0 test). If you are on a         new Apple device, follow these steps to upgrade to the latest         Firefox.
      - Pinch zooming will now be supported for our users with         Windows touchscreen devices and touchpads on Mac devices.
        Firefox users may now use pinch to zoom on touch-capable         devices to zoom in and out of webpages.
      - Weve improved functionality and design for a number of         Firefox search features:
        * Selecting a search engine at the bottom of the search           panel now enters search mode for that engine, allowing you to           see suggestions (if available) for your search terms. The old           behavior (immediately performing a search) is available with           a shift-click.
        * When Firefox autocompletes the URL of one of your search           engines, you can now search with that engine directly in the           address bar by selecting the shortcut in the address bar           results.
        * Weve added buttons at the bottom of the search panel to           allow you to search your bookmarks, open tabs, and history.
      - Firefox supports AcroForm, which will allow you to fill in,         print, and save supported PDF forms and the PDF viewer also         has a new fresh look.
      - For our users in the US and Canada, Firefox can now save,         manage, and auto-fill credit card information for you, making         shopping on Firefox ever more convenient.
      - In addition to our default, dark and light themes, with         this release, Firefox introduces the Alpenglow theme: a         colorful appearance for buttons, menus, and windows. You can         update your Firefox themes under settings or preferences.
    * Changed: Firefox no longer supports Adobe Flash. There is no       setting available to re-enable Flash support.
    * Enterprise: Various bug fixes and new policies have been       implemented in the latest version of Firefox. See more       details in the Firefox for Enterprise 91 Release Notes.
