CVE-2022-34485

Estado: ModificadaCrítica (9.8)—

Los desarrolladores de Mozilla, Bryce Seager van Dyk y Mozilla Fuzzing Team, informaron sobre posibles vulnerabilidades presentes en Firefox 101. 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. Esta vulnerabilidad afecta a Firefox < 102.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
