CVSS: 4.3EPSS: 0%CPEs: 1EXPL: 1CVE-2021-29957 – Mozilla: Partial protection of inline OpenPGP message not indicated
https://notcve.org/view.php?id=CVE-2021-29957
07 Jun 2021 — If a MIME encoded email contains an OpenPGP inline signed or encrypted message part, but also contains an additional unprotected part, Thunderbird did not indicate that only parts of the message are protected. This vulnerability affects Thunderbird < 78.10.2. Si un correo electrónico codificado con MIME contiene una parte del mensaje firmada o cifrada con OpenPGP en línea, pero también contiene una parte adicional no protegida, Thunderbird no indicaba que sólo algunas partes del mensaje estaban protegidas. ... • https://bugzilla.mozilla.org/show_bug.cgi?id=1673241 • CWE-347: Improper Verification of Cryptographic Signature •

03 Jun 2021 — Mozilla developers reported memory safety bugs present in Firefox 88 and Firefox ESR 78.11. 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 < 78.11, Firefox < 89, and Firefox ESR < 78.11.

https://notcve.org/view.php?id=CVE-2021-29951
11 May 2021 — The Mozilla Maintenance Service granted SERVICE_START access to BUILTIN|Users which, in a domain network, grants normal remote users access to start or stop the service. This could be used to prevent the browser update service from operating (if an attacker spammed the 'Stop' command); but also exposed attack surface in the maintenance service. *Note: This issue only affected Windows operating systems older than Win 10 build 1709. Other operating systems are unaffected.*. This vulnerability affects Thunderb... • https://packetstorm.news/files/id/162522 • CWE-269: Improper Privilege Management •

https://notcve.org/view.php?id=CVE-2021-29950
06 May 2021 — Thunderbird unprotects a secret OpenPGP key prior to using it for a decryption, signing or key import task. If the task runs into a failure, the secret key may remain in memory in its unprotected state. This vulnerability affects Thunderbird < 78.8.1. Thunderbird desprotege una clave secreta OpenPGP antes de usarla para una tarea de descifrado, firma o importación de claves. Si la tarea ejecuta un fallo, la clave secreta puede permanecer en la memoria en su estado desprotegido. • https://bugzilla.mozilla.org/show_bug.cgi?id=1673239 • CWE-312: Cleartext Storage of Sensitive Information CWE-522: Insufficiently Protected Credentials •

28 Apr 2021 — When loading the shared library that provides the OTR protocol implementation, Thunderbird will initially attempt to open it using a filename that isn't distributed by Thunderbird. If a computer has already been infected with a malicious library of the alternative filename, and the malicious library has been copied to a directory that is contained in the search path for executable libraries, then Thunderbird will load the incorrect library.

https://notcve.org/view.php?id=CVE-2021-29945
26 Apr 2021 — The WebAssembly JIT could miscalculate the size of a return type, which could lead to a null read and result in a crash. *Note: This issue only affected x86-32 platforms. Other platforms are unaffected.*. This vulnerability affects Firefox ESR < 78.10, Thunderbird < 78.10, and Firefox < 88.

26 Apr 2021 — Ports that were written as an integer overflow above the bounds of a 16-bit integer could have bypassed port blocking restrictions when used in the Alt-Svc header. This vulnerability affects Firefox ESR < 78.10, Thunderbird < 78.10, and Firefox < 88.

26 Apr 2021 — Signatures are written to disk before and read during verification, which might be subject to a race condition when a malicious local process or user is replacing the file. This vulnerability affects Thunderbird < 78.10. Las firmas son escritas en el disco antes y se leen durante la verificación, lo que podría estar sujeto a una condición de carrera cuando un proceso local malicioso o un usuario está reemplazando el archivo.

26 Apr 2021 — When Responsive Design Mode was enabled, it used references to objects that were previously freed. We presume that with enough effort this could have been exploited to run arbitrary code. This vulnerability affects Firefox ESR < 78.10, Thunderbird < 78.10, and Firefox < 88.
