https://notcve.org/view.php?id=CVE-2022-45406
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. The Mozilla Foundation Security Advisory describes this flaw as: 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.

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. Al resolver un enlace simbólico como <code>file:///proc/self/fd/1</code>, se puede producir un mensaje de error donde el enlace simbólico se resolvió en una cadena que contiene memoria no inicializada en el búfer. • https://bugzilla.mozilla.org/show_bug.cgi?id=1791029 https://www.mozilla.org/security/advisories/mfsa2022-47 https://www.mozilla.org/security/advisories/mfsa2022-48 https://www.mozilla.org/security/advisories/mfsa2022-49 https://access.redhat.com/security/cve/CVE-2022-45412 https://bugzilla.redhat.com/show_bug.cgi?id=2143205 • CWE-59: Improper Link Resolution Before File Access ('Link Following') CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

https://notcve.org/view.php?id=CVE-2022-45421
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.

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.

CVSS: 6.1EPSS: 0%CPEs: 3EXPL: 0CVE-2022-45411 – Mozilla: Cross-Site Tracing was possible via non-standard override headers
https://notcve.org/view.php?id=CVE-2022-45411
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. El seguimiento entre sitios se produce cuando un servidor repite una solicitud a través del método Trace, lo que permite que un ataque XSS acceda a encabezados de autorización y cookies inaccesibles para JavaScript (como las cookies protegidas por HTTPOnly). • https://bugzilla.mozilla.org/show_bug.cgi?id=1790311 https://www.mozilla.org/security/advisories/mfsa2022-47 https://www.mozilla.org/security/advisories/mfsa2022-48 https://www.mozilla.org/security/advisories/mfsa2022-49 https://access.redhat.com/security/cve/CVE-2022-45411 https://bugzilla.redhat.com/show_bug.cgi?id=2143204 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
