CVE-2019-8508

Estado: ModificadaAlta (7.8)—

Un desbordamiento del búfer fue abordado mejorando la comprobación de límites. Este problema es corregido en macOS Mojave versión 10.14.4. Montar un recurso compartido de red NFS diseñado maliciosamente puede conllevar a una ejecución de código arbitrario con privilegios system.

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).
