CVE-2016-7420

Estado: ModificadaMedia (5.9)—

Crypto++ (también conocido como cryptopp) hasta la versión 5.6.4 no documenta el requisito para una definición NDEBUG de tiempo de compilación deshabilitando las múltiples llamadas assert que son no intencionadas en uso de producción, lo que podría permitir a atacantes dependientes del contexto obtener información sensible aprovechando acceso a la memoria de procesamiento después de un fallo de aserción, según lo demostrado mediante la lectura de un volcado de memoria.

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).
