CVE-2016-8334

Estado: ModificadaBaja (3.3)—

Una gran vulnerabilidad de lectura fuera de límites en la memoria dinámica en Foxit PDF Reader puede ser potencialmente abusado para divulgación de información. Combinado con otra vulnerabilidad, puede ser empleado para filtrar el diseño de la memoria dinámica y en la elusión de ASLR.

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).
