CVE-2018-4124

Estado: ModificadaCrítica (9.8)—💥 PoC

Se ha descubierto un problema en algunos productos Apple. Las versiones de iOS anteriores a la 11.2.6, las versiones de macOS anteriores a la 10.13.3 Supplemental Update, las versiones de tvOS anteriores a la 11.2.6 y las versiones de watchOS anteriores a la 4.2.3 se han visto afectadas. El problema afecta al componente "CoreText". Permite que atacantes remotos provoquen una denegación de servicio (corrupción de memoria y cierre inesperado del sistema) o, posiblemente, otro impacto no especificado mediante una cadena manipulada que contenga un carácter Telugu determinado.

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).

💥 Exploits públicos

Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.

⚠️ Las pruebas de concepto de GitHub no están verificadas: algunas son falsas o contienen malware. No las ejecute nunca fuera de un laboratorio aislado.
