The version of Thunderbird installed on the remote macOS or Mac OS X host is prior to 91.5. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2022-03 advisory.

  - A race condition could have allowed bypassing the fullscreen notification which could have lead to a     fullscreen window spoof being unnoticed. This bug only affects Firefox for Windows. Other operating     systems are unaffected. (CVE-2022-22746)

  - When navigating from inside an iframe while requesting fullscreen access, an attacker-controlled tab could     have made the browser unable to leave fullscreen mode. (CVE-2022-22743)

  - When inserting text while in edit mode, some characters might have lead to out-of-bounds memory access     causing a potentially exploitable crash. (CVE-2022-22742)

  - When resizing a popup while requesting fullscreen access, the popup would have become unable to leave     fullscreen mode. (CVE-2022-22741)

  - Certain network request objects were freed too early when releasing a network request handle. This could     have lead to a use-after-free causing a potentially exploitable crash. (CVE-2022-22740)

  - Applying a CSS filter effect could have accessed out of bounds memory. This could have lead to a heap-     buffer-overflow causing a potentially exploitable crash. (CVE-2022-22738)

  - Constructing audio sinks could have lead to a race condition when playing audio files and closing windows.
    This could have lead to a use-after-free causing a potentially exploitable crash. (CVE-2022-22737)

  - It was possible to construct specific XSLT markup that would be able to bypass an iframe sandbox.
    (CVE-2021-4140)

  - Malicious websites could have confused Firefox into showing the wrong origin when asking to launch a     program and handling an external URL protocol. (CVE-2022-22748)

  - Securitypolicyviolation events could have leaked cross-origin information for frame-ancestors violations     (CVE-2022-22745)

  - The constructed curl command from the Copy as curl feature in DevTools was not properly escaped for     PowerShell.  This could have lead to command injection if pasted into a Powershell prompt. This bug only     affects Thunderbird for Windows. Other operating systems are unaffected. (CVE-2022-22744)

  - After accepting an untrusted certificate, handling an empty pkcs7 sequence as part of the certificate data     could have lead to a crash. This crash is believed to be unexploitable. (CVE-2022-22747)

  - Malicious websites could have tricked users into accepting launching a program to handle an external URL     protocol. (CVE-2022-22739)

  - Mozilla developers Calixte Denizet, Kershaw Chang, Christian Holler, Jason Kratzer, Gabriele Svelto, Tyson     Smith, Simon Giesecke, and Steve Fink reported memory safety bugs present in Firefox 95 and Firefox ESR     91.4. 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. (CVE-2022-22751)

The version of thunderbird installed on the remote host is prior to 91.6.0-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2022-1818 advisory.

    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)

    During operations on MessageTasks, a task may have been removed while it was still scheduled, resulting in     memory corruption and a potentially exploitable crash. This vulnerability affects Thunderbird < 78.15,     Thunderbird < 91.2, Firefox ESR < 91.2, Firefox ESR < 78.15, and Firefox < 93. (CVE-2021-38496)

    Through use of reportValidity() and window.open(), a plain-text validation message could have been     overlaid on another origin, leading to possible user confusion and spoofing attacks. This vulnerability     affects Firefox < 93, Thunderbird < 91.2, and Firefox ESR < 91.2. (CVE-2021-38497)

    During process shutdown, a document could have caused a use-after-free of a languages service object,     leading to memory corruption and a potentially exploitable crash. This vulnerability affects Firefox < 93,     Thunderbird < 91.2, and Firefox ESR < 91.2. (CVE-2021-38498)

    Mozilla developers reported memory safety bugs present in Firefox 92 and Firefox ESR 91.1. 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 < 78.15, Thunderbird < 91.2,     Firefox ESR < 91.2, Firefox ESR < 78.15, and Firefox < 93. (CVE-2021-38500)

    Mozilla developers reported memory safety bugs present in Firefox 92 and Firefox ESR 91.1. 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 < 93, Thunderbird < 91.2, and     Firefox ESR < 91.2. (CVE-2021-38501)

    Thunderbird ignored the configuration to require STARTTLS security for an SMTP connection. A MITM could     perform a downgrade attack to intercept transmitted messages, or could take control of the authenticated     session to execute SMTP commands chosen by the MITM. If an unprotected authentication method was     configured, the MITM could obtain the authentication credentials, too. This vulnerability affects     Thunderbird < 91.2. (CVE-2021-38502)

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 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.

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)

  - 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)

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

  - 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)

  - 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)

  - During operations on MessageTasks, a task may have been removed while it was still scheduled, resulting in     memory corruption and a potentially exploitable crash. This vulnerability affects Thunderbird < 78.15,     Thunderbird < 91.2, Firefox ESR < 91.2, Firefox ESR < 78.15, and Firefox < 93. (CVE-2021-38496)

  - Through use of reportValidity() and window.open(), a plain-text validation message could have been     overlaid on another origin, leading to possible user confusion and spoofing attacks. This vulnerability     affects Firefox < 93, Thunderbird < 91.2, and Firefox ESR < 91.2. (CVE-2021-38497)

  - During process shutdown, a document could have caused a use-after-free of a languages service object,     leading to memory corruption and a potentially exploitable crash. This vulnerability affects Firefox < 93,     Thunderbird < 91.2, and Firefox ESR < 91.2. (CVE-2021-38498)
