CVSS: 8.8EPSS: 0%CPEs: 3EXPL: 0CVE-2022-22764 – Mozilla: Memory safety bugs fixed in Firefox 97 and Firefox ESR 91.6
https://notcve.org/view.php?id=CVE-2022-22764
Mozilla developers Paul Adenot and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox 96 and Firefox ESR 91.5. 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 < 97, Thunderbird < 91.6, and Firefox ESR < 91.6. Los desarrolladores de Mozilla, Paul Adenot y Mozilla Fuzzing Team, informaron sobre errores de seguridad de la memoria presentes en Firefox 96 y Firefox ESR 91.5. Algunos de estos errores mostraron evidencia de corrupción de memoria y suponemos que con suficiente esfuerzo algunos de ellos podrían haberse aprovechado para ejecutar código arbitrario. • https://bugzilla.mozilla.org/buglist.cgi?bug_id=1742682%2C1744165%2C1746545%2C1748210%2C1748279 https://www.mozilla.org/security/advisories/mfsa2022-04 https://www.mozilla.org/security/advisories/mfsa2022-05 https://www.mozilla.org/security/advisories/mfsa2022-06 https://access.redhat.com/security/cve/CVE-2022-22764 https://bugzilla.redhat.com/show_bug.cgi?id=2053243 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-787: Out-of-bounds Write •
CVSS: 8.8EPSS: 0%CPEs: 3EXPL: 1CVE-2022-22756 – Mozilla: Drag and dropping an image could have resulted in the dropped object being an executable
https://notcve.org/view.php?id=CVE-2022-22756
If a user was convinced to drag and drop an image to their desktop or other folder, the resulting object could have been changed into an executable script which would have run arbitrary code after the user clicked on it. This vulnerability affects Firefox < 97, Thunderbird < 91.6, and Firefox ESR < 91.6. Si se convenciera a un usuario de arrastrar y soltar una imagen en su escritorio u otra carpeta, el objeto resultante podría haberse convertido en un script ejecutable que habría ejecutado código arbitrario después de que el usuario hiciera clic en él. Esta vulnerabilidad afecta a Firefox < 97, Thunderbird < 91.6 y Firefox ESR < 91.6. The Mozilla Foundation Security Advisory describes this flaw as: If a user was convinced to drag and drop an image to their desktop or other folder, the resulting object could have been changed into an executable script, which would have run arbitrary code after the user clicked it. • https://bugzilla.mozilla.org/show_bug.cgi?id=1317873 https://www.mozilla.org/security/advisories/mfsa2022-04 https://www.mozilla.org/security/advisories/mfsa2022-05 https://www.mozilla.org/security/advisories/mfsa2022-06 https://access.redhat.com/security/cve/CVE-2022-22756 https://bugzilla.redhat.com/show_bug.cgi?id=2053237 • CWE-1021: Improper Restriction of Rendered UI Layers or Frames •

Thunderbird versions prior to 91.3.0 are vulnerable to the heap overflow described in CVE-2021-43527 when processing S/MIME messages. Thunderbird versions 91.3.0 and later will not call the vulnerable code when processing S/MIME messages that contain certificates with DER-encoded DSA or RSA-PSS signatures. A flaw was found in Thunderbird, which is vulnerable to the heap overflow described in CVE-2021-43527 when processing S/MIME messages.

CVSS: 6.5EPSS: 0%CPEs: 1EXPL: 0CVE-2021-4126
https://notcve.org/view.php?id=CVE-2021-4126
When receiving an OpenPGP/MIME signed email message that contains an additional outer MIME message layer, for example a message footer added by a mailing list gateway, Thunderbird only considered the inner signed message for the signature validity. This gave the false impression that the additional contents were also covered by the digital signature. Starting with Thunderbird version 91.4.1, only the signature that belongs to the top level MIME part will be considered for the displayed status. This vulnerability affects Thunderbird < 91.4.1. Al recibir un mensaje de correo electrónico firmado con OpenPGP/MIME que contiene una capa de mensaje MIME externa adicional, por ejemplo un pie de página de mensaje agregado por una puerta de enlace de lista de correo, Thunderbird solo consideró el mensaje firmado interno para la validez de la firma. • https://bugzilla.mozilla.org/show_bug.cgi?id=1732310 https://www.mozilla.org/security/advisories/mfsa2021-55 •
CVSS: 6.5EPSS: 0%CPEs: 3EXPL: 0CVE-2022-22747 – Mozilla: Crash when handling empty pkcs7 sequence
https://notcve.org/view.php?id=CVE-2022-22747
After accepting an untrusted certificate, handling an empty pkcs7 sequence as part of the certificate data could have lead to a crash. This crash is believed to be unexploitable. This vulnerability affects Firefox ESR < 91.5, Firefox < 96, and Thunderbird < 91.5. Después de aceptar un certificado que no es de confianza, manejar una secuencia pkcs7 vacía como parte de los datos del certificado podría haber provocado un bloqueo. Se cree que este accidente no es explotable. • https://bugzilla.mozilla.org/show_bug.cgi?id=1735028 https://www.mozilla.org/security/advisories/mfsa2022-01 https://www.mozilla.org/security/advisories/mfsa2022-02 https://www.mozilla.org/security/advisories/mfsa2022-03 https://access.redhat.com/security/cve/CVE-2022-22747 https://bugzilla.redhat.com/show_bug.cgi?id=2039572 • CWE-295: Improper Certificate Validation CWE-476: NULL Pointer Dereference •
