CVE-2016-5170

Estado: ModificadaAlta (8.8)—

WebKit/Source/bendengs/modules/v8/V8BendengForModules.cpp en Blink, como se usa en Google Chrome en versiones anteriores a 53.0.2785.113, no considera correctamente los efectos secundarios de los captadores durante la conversión de clave del array, lo que permite a atacantes remotos provocar una denegación de servicio (uso después de liberación de memoria) o tener otro posible impacto no especificado a través de llamadas API Indexed Database (también conocido como IndexedDB).

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).
