  - Mozilla developers and community members Julian Hector, Randell Jesup, Gabriele Svelto, Tyson Smith,     Christian Holler, and Masayuki Nakano reported memory safety bugs present in Firefox 94. 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 < 95, Firefox ESR < 91.4.0, and     Thunderbird < 91.4.0. (CVE-2021-4129)

  - Thunderbird unexpectedly enabled JavaScript in the composition area. The JavaScript execution context was     limited to this area and did not receive chrome-level privileges, but could be used as a stepping stone to     further an attack with other vulnerabilities. This vulnerability affects Thunderbird < 91.4.0.
    (CVE-2021-43528)

  - Under certain circumstances, asynchronous functions could have caused a navigation to fail but expose the     target URL. This vulnerability affects Thunderbird < 91.4.0, Firefox ESR < 91.4.0, and Firefox < 95.
    (CVE-2021-43536)

  - An incorrect type conversion of sizes from 64bit to 32bit integers allowed an attacker to corrupt memory     leading to a potentially exploitable crash. This vulnerability affects Thunderbird < 91.4.0, Firefox ESR <     91.4.0, and Firefox < 95. (CVE-2021-43537)

  - 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)

  - When invoking protocol handlers for external protocols, a supplied parameter URL containing spaces was not     properly escaped. This vulnerability affects Thunderbird < 91.4.0, Firefox ESR < 91.4.0, and Firefox < 95.
    (CVE-2021-43541)

  - Using XMLHttpRequest, an attacker could have identified installed applications by probing error messages     for loading external protocols. This vulnerability affects Thunderbird < 91.4.0, Firefox ESR < 91.4.0, and     Firefox < 95. (CVE-2021-43542)

  - Documents loaded with the CSP sandbox directive could have escaped the sandbox's script restriction by     embedding additional content. This vulnerability affects Thunderbird < 91.4.0, Firefox ESR < 91.4.0, and     Firefox < 95. (CVE-2021-43543)

  - Using the Location API in a loop could have caused severe application hangs and crashes. This     vulnerability affects Thunderbird < 91.4.0, Firefox ESR < 91.4.0, and Firefox < 95. (CVE-2021-43545)

  - It was possible to recreate previous cursor spoofing attacks against users with a zoomed native cursor.

The remote NewStart CGSL host, running version MAIN 6.02, has firefox packages installed that are affected by multiple vulnerabilities:

  - In Expat (aka libexpat) before 2.4.5, there is an integer overflow in storeRawNames. (CVE-2022-25315)

  - It was possible to construct specific XSLT markup that would be able to bypass an iframe sandbox. This     vulnerability affects Firefox ESR < 91.5, Firefox < 96, and Thunderbird < 91.5. (CVE-2021-4140)

  - crossbeam-deque is a package of work-stealing deques for building task schedulers when programming in     Rust. In versions prior to 0.7.4 and 0.8.0, the result of the race condition is that one or more tasks in     the worker queue can be popped twice instead of other tasks that are forgotten and never popped. If tasks     are allocated on the heap, this can cause double free and a memory leak. If not, this still can cause a     logical bug. Crates using `Stealer::steal`, `Stealer::steal_batch`, or `Stealer::steal_batch_and_pop` are     affected by this issue. This has been fixed in crossbeam-deque 0.8.1 and 0.7.4. (CVE-2021-32810)

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)

Other operating systems are unaffected.*     This vulnerability affects Thunderbird < 78.13, Thunderbird < 91, Firefox ESR < 78.13, and Firefox < 91.
    (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. 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)

  - Mozilla developers and community members reported memory safety bugs present in Firefox 90.

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)

  - Under certain circumstances, asynchronous functions could have caused a navigation to fail but expose the     target URL. This vulnerability affects Thunderbird < 91.4.0, Firefox ESR < 91.4.0, and Firefox < 95.
    (CVE-2021-43536)

  - 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)

    (CVE-2021-43541)

  - Using XMLHttpRequest, an attacker could have identified installed applications by probing error messages     for loading external protocols. This vulnerability affects Thunderbird < 91.4.0, Firefox ESR < 91.4.0, and     Firefox < 95. (CVE-2021-43542)

  - Documents loaded with the CSP sandbox directive could have escaped the sandbox's script restriction by     embedding additional content. This vulnerability affects Thunderbird < 91.4.0, Firefox ESR < 91.4.0, and     Firefox < 95. (CVE-2021-43543)

  - Using the Location API in a loop could have caused severe application hangs and crashes. This     vulnerability affects Thunderbird < 91.4.0, Firefox ESR < 91.4.0, and Firefox < 95. (CVE-2021-43545)

  - It was possible to recreate previous cursor spoofing attacks against users with a zoomed native cursor.
    This vulnerability affects Thunderbird < 91.4.0, Firefox ESR < 91.4.0, and Firefox < 95. (CVE-2021-43546)

The version of Thunderbird installed on the remote macOS or Mac OS X host is prior to 91.4.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2021-54 advisory.

  - Under certain circumstances, asynchronous functions could have caused a navigation to fail but expose the     target URL. (CVE-2021-43536)

  - An incorrect type conversion of sizes from 64bit to 32bit integers allowed an attacker to corrupt memory     leading to a potentially exploitable crash. (CVE-2021-43537)

  - 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. (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. (CVE-2021-43539)

  - When invoking protocol handlers for external protocols, a supplied parameter URL containing spaces was not     properly escaped. (CVE-2021-43541)

  - Using XMLHttpRequest, an attacker could have identified installed applications by probing error messages     for loading external protocols. (CVE-2021-43542)

  - Documents loaded with the CSP sandbox directive could have escaped the sandbox's script restriction by     embedding additional content. (CVE-2021-43543)

  - Using the Location API in a loop could have caused severe application hangs and crashes. (CVE-2021-43545)

  - It was possible to recreate previous cursor spoofing attacks against users with a zoomed native cursor.
    (CVE-2021-43546)

  - Thunderbird unexpectedly enabled JavaScript in the composition area. The JavaScript execution context was     limited to this area and did not receive chrome-level privileges, but could be used as a stepping stone to     further an attack with other vulnerabilities. (CVE-2021-43528)
