  - 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.

The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2021:3155 advisory.

  - Uninitialized memory in a canvas object could have caused an incorrect free() leading to memory corruption     and a potentially exploitable crash. This vulnerability affects Thunderbird < 78.13, Thunderbird < 91,     Firefox ESR < 78.13, and Firefox < 91. (CVE-2021-29980)

  - Instruction reordering resulted in a sequence of instructions that would cause an object to be incorrectly     considered during garbage collection. This led to memory corruption and a potentially exploitable crash.
    This vulnerability affects Thunderbird < 78.13, Thunderbird < 91, Firefox ESR < 78.13, and Firefox < 91.
    (CVE-2021-29984)

  - A use-after-free vulnerability in media channels could have led to memory corruption and a potentially     exploitable crash. This vulnerability affects Thunderbird < 78.13, Thunderbird < 91, Firefox ESR < 78.13,     and Firefox < 91. (CVE-2021-29985)

  - A suspected race condition when calling getaddrinfo led to memory corruption and a potentially exploitable     crash. *Note: This issue only affected Linux operating systems. Other operating systems are unaffected.*     This vulnerability affects Thunderbird < 78.13, Thunderbird < 91, Firefox ESR < 78.13, and Firefox < 91.
    (CVE-2021-29986)

  - 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. 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 < 78.13, Firefox ESR < 78.13,     and Firefox < 91. (CVE-2021-29989)

    * 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.
