CVE-2016-9400

Estado: ModificadaCrítica (9.8)—

El método CClient::ProcessServerPacket en engine/client/client.cpp en Teeworlds en versiones anteriores a 0.6.4 permite a servidores remotos escribir en ubicaciones de memoria física arbitrarias y posiblemente ejecutar código arbitrario a través de vectores que involucran manipulación rápida.

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).
