CVSS: 8.8EPSS: 0%CPEs: 3EXPL: 1CVE-2021-29970 – Mozilla: Use-after-free in accessibility features of a document
https://notcve.org/view.php?id=CVE-2021-29970
A malicious webpage could have triggered a use-after-free, memory corruption, and a potentially exploitable crash. *This bug could only be triggered when accessibility was enabled.*. This vulnerability affects Thunderbird < 78.12, Firefox ESR < 78.12, and Firefox < 90. Una página web maliciosa podría desencadenar un uso de memoria previamente liberada, una corrupción de memoria y un bloqueo potencialmente explotable. *Este bug sólo podía ser desencadenado cuando la accesibilidad estaba activada. • https://bugzilla.mozilla.org/show_bug.cgi?id=1709976 https://security.gentoo.org/glsa/202202-03 https://security.gentoo.org/glsa/202208-14 https://www.mozilla.org/security/advisories/mfsa2021-28 https://www.mozilla.org/security/advisories/mfsa2021-29 https://www.mozilla.org/security/advisories/mfsa2021-30 https://access.redhat.com/security/cve/CVE-2021-29970 https://bugzilla.redhat.com/show_bug.cgi?id=1982013 • CWE-416: Use After Free CWE-787: Out-of-bounds Write •
CVSS: 8.8EPSS: 0%CPEs: 3EXPL: 0CVE-2021-29976 – Mozilla: Memory safety bugs fixed in Firefox 90 and Firefox ESR 78.12
https://notcve.org/view.php?id=CVE-2021-29976
Mozilla developers reported memory safety bugs present in code shared between Firefox and Thunderbird. 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 < 78.12, Firefox ESR < 78.12, and Firefox < 90. Los desarrolladores de Mozilla informaron de fallos de seguridad de memoria presentes en el código compartido entre Firefox y Thunderbird. Algunos de estos fallos mostraban evidencias de corrupción de memoria y suponemos que con suficiente esfuerzo algunos de ellos podrían haber sido explotados para ejecutar código arbitrario. • https://bugzilla.mozilla.org/buglist.cgi?bug_id=1700895%2C1703334%2C1706910%2C1711576%2C1714391 https://security.gentoo.org/glsa/202202-03 https://security.gentoo.org/glsa/202208-14 https://www.mozilla.org/security/advisories/mfsa2021-28 https://www.mozilla.org/security/advisories/mfsa2021-29 https://www.mozilla.org/security/advisories/mfsa2021-30 https://access.redhat.com/security/cve/CVE-2021-29976 https://bugzilla.redhat.com/show_bug.cgi?id=1982014 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2021-29964
A locally-installed hostile program could send `WM_COPYDATA` messages that Firefox would process incorrectly, leading to an out-of-bounds read. *This bug only affects Firefox on Windows. Other operating systems are unaffected.*. This vulnerability affects Thunderbird < 78.11, Firefox < 89, and Firefox ESR < 78.11. Un programa hostil instalado localmente podría enviar mensajes "WM_COPYDATA" que Firefox procesaría incorrectamente, conllevando una lectura fuera de límites. • https://bugzilla.mozilla.org/show_bug.cgi?id=1706501 https://www.mozilla.org/security/advisories/mfsa2021-23 https://www.mozilla.org/security/advisories/mfsa2021-24 https://www.mozilla.org/security/advisories/mfsa2021-26 • CWE-125: Out-of-bounds Read •
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
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. Esta vulnerabilidad afecta a Thunderbird versiones anteriores a 78.10.2 • https://bugzilla.mozilla.org/show_bug.cgi?id=1673241 https://www.mozilla.org/security/advisories/mfsa2021-22 https://access.redhat.com/security/cve/CVE-2021-29957 https://bugzilla.redhat.com/show_bug.cgi?id=1961503 • CWE-347: Improper Verification of Cryptographic Signature •
