CVE-2018-5251

Estado: ModificadaMedia (6.5)—

En libming 0.4.8, hay una vulnerabilidad de error en la propiedad signedness de un número entero (desplazamiento izquierdo de un valor negativo) en la función readSBits (util/read.c). Los atacantes remotos pueden aprovechar esta vulnerabilidad para provocar una denegación de servicio (DoS) mediante un archivo swf manipulado.

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).
