CVE-2016-7544

Estado: ModificadaAlta (7.5)—

Crypto ++ 5.6.4 utiliza incorrectamente las funciones basadas en pila _malloca y _freea de Microsoft. La biblioteca solicitará un bloqueo de memoria para alinear una tabla en la memoria. Si la tabla se reasigna más tarde, entonces se podría liberar el puntero incorrecto.

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).
