CVSS: 2.5EPSS: 0%CPEs: 1EXPL: 1CVE-2021-29948 – Mozilla: Race condition when reading from disk while verifying signatures
https://notcve.org/view.php?id=CVE-2021-29948
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. Esta vulnerabilidad afecta a Thunderbird versiones anteriores a 78.10 • https://bugzilla.mozilla.org/show_bug.cgi?id=1692899 https://www.mozilla.org/security/advisories/mfsa2021-14 https://access.redhat.com/security/cve/CVE-2021-29948 https://bugzilla.redhat.com/show_bug.cgi?id=1951381 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition •

https://notcve.org/view.php?id=CVE-2021-29945
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. El JIT de WebAssembly podía calcular mal el tamaño de un tipo de retorno, lo que podía conllevar a una lectura nula y resultar en un bloqueo. • https://bugzilla.mozilla.org/show_bug.cgi?id=1700690 https://www.mozilla.org/security/advisories/mfsa2021-14 https://www.mozilla.org/security/advisories/mfsa2021-15 https://www.mozilla.org/security/advisories/mfsa2021-16 https://access.redhat.com/security/cve/CVE-2021-29945 https://bugzilla.redhat.com/show_bug.cgi?id=1951370 • CWE-476: NULL Pointer Dereference CWE-682: Incorrect Calculation •
CVSS: 6.5EPSS: 0%CPEs: 1EXPL: 0CVE-2021-23993 – Mozilla: Inability to send encrypted OpenPGP email after importing a crafted OpenPGP key
https://notcve.org/view.php?id=CVE-2021-23993
An attacker may perform a DoS attack to prevent a user from sending encrypted email to a correspondent. If an attacker creates a crafted OpenPGP key with a subkey that has an invalid self signature, and the Thunderbird user imports the crafted key, then Thunderbird may try to use the invalid subkey, but the RNP library rejects it from being used, causing encryption to fail. This vulnerability affects Thunderbird < 78.9.1. Un atacante puede llevar a cabo un ataque DoS para impedir a un usuario de enviar un correo electrónico cifrado a un corresponsal. Si un atacante crea una clave OpenPGP diseñada con una subclave que presenta una autofirma no válida, y el usuario de Thunderbird importa la clave diseñada, entonces Thunderbird puede intentar usar la subclave no válida, pero la biblioteca RNP lo rechaza para ser usado, causando que el cifrado presente un fallo. • https://bugzilla.mozilla.org/show_bug.cgi?id=1666360 https://www.mozilla.org/security/advisories/mfsa2021-13 https://access.redhat.com/security/cve/CVE-2021-23993 https://bugzilla.redhat.com/show_bug.cgi?id=1948395 • CWE-347: Improper Verification of Cryptographic Signature •
