CVE-2021-0621

Estado: ModificadaMedia (5.5)—

En asf extractor, se presenta una posible lectura fuera de límites debido a un desbordamiento de enteros. Esto podría conllevar a una divulgación de información local sin ser necesarios privilegios de ejecución adicionales. No es requerida una interacción del usuario para su explotación. ID del Parche: ALPS05489178; ID del Problema: ALPS05561383.

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).
