"The version of firefox installed on the remote host is prior to 102.5.0-1. It is, therefore, affected by multiple
vulnerabilities as referenced in the ALAS2FIREFOX-2023-009 advisory.

  - Service Workers should not be able to infer information about opaque cross-origin responses; but timing
    information for cross-origin media combined with Range requests might have allowed them to determine the
    presence or length of a media file. This vulnerability affects Firefox ESR < 102.5, Thunderbird < 102.5,
    and Firefox < 107. (CVE-2022-45403)

  - Through a series of popup and <code>window.print()</code> calls, an attacker can cause a window to go
    fullscreen without the user seeing the notification prompt, resulting in potential user confusion or
    spoofing attacks. This vulnerability affects Firefox ESR < 102.5, Thunderbird < 102.5, and Firefox < 107.
    (CVE-2022-45404)

  - Freeing arbitrary <code>nsIInputStream</code>'s on a different thread than creation could have led to a
    use-after-free and potentially exploitable crash. This vulnerability affects Firefox ESR < 102.5,
    Thunderbird < 102.5, and Firefox < 107. (CVE-2022-45405)

  - If an out-of-memory condition occurred when creating a JavaScript global, a JavaScript realm may be
    deleted while references to it lived on in a BaseShape. This could lead to a use-after-free causing a
    potentially exploitable crash. This vulnerability affects Firefox ESR < 102.5, Thunderbird < 102.5, and
    Firefox < 107. (CVE-2022-45406)

  - Through a series of popups that reuse windowName, an attacker can cause a window to go fullscreen without
    the user seeing the notification prompt, resulting in potential user confusion or spoofing attacks. This
    vulnerability affects Firefox ESR < 102.5, Thunderbird < 102.5, and Firefox < 107. (CVE-2022-45408)

  - The garbage collector could have been aborted in several states and zones and
    <code>GCRuntime::finishCollection</code> may not have been called, leading to a use-after-free and
    potentially exploitable crash. This vulnerability affects Firefox ESR < 102.5, Thunderbird < 102.5, and
    Firefox < 107. (CVE-2022-45409)

  - When a ServiceWorker intercepted a request with <code>FetchEvent</code>, the origin of the request was
    lost after the ServiceWorker took ownership of it. This had the effect of negating SameSite cookie
    protections. This was addressed in the spec and then in browsers. This vulnerability affects Firefox ESR <
    102.5, Thunderbird < 102.5, and Firefox < 107. (CVE-2022-45410)

  - Cross-Site Tracing occurs when a server will echo a request back via the Trace method, allowing an XSS
    attack to access to authorization headers and cookies inaccessible to JavaScript (such as cookies
    protected by HTTPOnly). To mitigate this attack, browsers placed limits on <code>fetch()</code> and
    XMLHttpRequest; however some webservers have implemented non-standard headers such as <code>X-Http-Method-
    Override</code> that override the HTTP method, and made this attack possible again. Thunderbird has
    applied the same mitigations to the use of this and similar headers. This vulnerability affects Firefox
    ESR < 102.5, Thunderbird < 102.5, and Firefox < 107. (CVE-2022-45411)

  - When resolving a symlink such as <code>file:///proc/self/fd/1</code>, an error message may be produced
    where the symlink was resolved to a string containing unitialized memory in the buffer. <br>*This bug only
    affects Thunderbird on Unix-based operated systems (Android, Linux, MacOS). Windows is unaffected.*. This
    vulnerability affects Firefox ESR < 102.5, Thunderbird < 102.5, and Firefox < 107. (CVE-2022-45412)

  - Keyboard events reference strings like KeyA that were at fixed, known, and widely-spread addresses.
    Cache-based timing attacks such as Prime+Probe could have possibly figured out which keys were being
    pressed. This vulnerability affects Firefox ESR < 102.5, Thunderbird < 102.5, and Firefox < 107.
    (CVE-2022-45416)

  - If a custom mouse cursor is specified in CSS, under certain circumstances the cursor could have been drawn
    over the browser UI, resulting in potential user confusion or spoofing attacks. This vulnerability affects
    Firefox ESR < 102.5, Thunderbird < 102.5, and Firefox < 107. (CVE-2022-45418)

  - Use tables inside of an iframe, an attacker could have caused iframe contents to be rendered outside the
    boundaries of the iframe, resulting in potential user confusion or spoofing attacks. This vulnerability
    affects Firefox ESR < 102.5, Thunderbird < 102.5, and Firefox < 107. (CVE-2022-45420)

  - Mozilla developers Andrew McCreight and Gabriele Svelto reported memory safety bugs present in Thunderbird
    102.4. 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. This vulnerability affects Firefox ESR < 102.5,
    Thunderbird < 102.5, and Firefox < 107. (CVE-2022-45421)
