CVE-2015-2313

Estado: ModificadaAlta (7.5)—

Sandstorm Cap’n Proto en versiones anteriores a la 0.4.1.1 y en versiones 0.5.x anteriores a la 0.5.1.2, cuando una aplicación invoca el método totalSize en un lector de objetos, permite que pares remotos provoquen una denegación de servicio (consumo de CPU) mediante un mensaje pequeño manipulado, que desencadena un "tight" en bucle. NOTA: Esta vulnerabilidad existe debido a una solución incompleta para CVE-2015-2312.

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).
