CVE-2023-4056

Estado: ModificadaCrítica (9.8)—

Fallos de seguridad de memoria presentes en Firefox 115, Firefox ESR 115.0, Firefox ESR 102.13, Thunderbird 115.0 y Thunderbird 102.13. Algunos de estos fallos mostraban evidencias de corrupción de memoria y suponemos que con el suficiente esfuerzo algunos de ellos podrían haber sido explotados para ejecutar código arbitrario. Esta vulnerabilidad afecta a versiones inferiores de Firefox 116, Firefox ESR 102.14, y Firefox ESR 115.1.

CVSS
