https://notcve.org/view.php?id=CVE-2023-6857
When resolving a symlink, a race may occur where the buffer passed to `readlink` may actually be smaller than necessary. *This bug only affects Firefox on Unix-based operating systems (Android, Linux, MacOS). Windows is unaffected.* This vulnerability affects Firefox ESR < 115.6, Thunderbird < 115.6, and Firefox < 121. Al resolver un enlace simbólico, puede ocurrir una ejecución en la que el búfer pase a "readlink" en realidad puede ser más pequeño de lo necesario. *Este error sólo afecta a Firefox en sistemas operativos basados en Unix (Android, Linux, MacOS).

CVSS: 7.5EPSS: 0%CPEs: 3EXPL: 0CVE-2023-50761 – Mozilla: S/MIME signature accepted despite mismatching message date
https://notcve.org/view.php?id=CVE-2023-50761
The signature of a digitally signed S/MIME email message may optionally specify the signature creation date and time. If present, Thunderbird did not compare the signature creation date with the message date and time, and displayed a valid signature despite a date or time mismatch. This could be used to give recipients the impression that a message was sent at a different date or time. This vulnerability affects Thunderbird < 115.6. La firma de un mensaje de correo electrónico S/MIME firmado digitalmente puede especificar opcionalmente la fecha y hora de creación de la firma. • https://bugzilla.mozilla.org/show_bug.cgi?id=1865647 https://lists.debian.org/debian-lts-announce/2023/12/msg00021.html https://www.debian.org/security/2023/dsa-5582 https://www.mozilla.org/security/advisories/mfsa2023-55 https://access.redhat.com/security/cve/CVE-2023-50761 https://bugzilla.redhat.com/show_bug.cgi?id=2255378 • CWE-347: Improper Verification of Cryptographic Signature •
CVSS: 7.5EPSS: 0%CPEs: 3EXPL: 0CVE-2023-50762 – Mozilla: Truncated signed text was shown with a valid OpenPGP signature
https://notcve.org/view.php?id=CVE-2023-50762
When processing a PGP/MIME payload that contains digitally signed text, the first paragraph of the text was never shown to the user. This is because the text was interpreted as a MIME message and the first paragraph was always treated as an email header section. A digitally signed text from a different context, such as a signed GIT commit, could be used to spoof an email message. This vulnerability affects Thunderbird < 115.6. Al procesar un payload PGP/MIME que contiene texto firmado digitalmente, el primer párrafo del texto nunca se mostró al usuario. • https://bugzilla.mozilla.org/show_bug.cgi?id=1862625 https://lists.debian.org/debian-lts-announce/2023/12/msg00021.html https://www.debian.org/security/2023/dsa-5582 https://www.mozilla.org/security/advisories/mfsa2023-55 https://access.redhat.com/security/cve/CVE-2023-50762 https://bugzilla.redhat.com/show_bug.cgi?id=2255379 • CWE-347: Improper Verification of Cryptographic Signature •
