CVE-2015-2141

Estado: ModificadaMedia (5)—

La función InvertibleRWFunction::CalculateInverse en rw.cpp en libcrypt++ 5.6.2 no ciega correctamente las operaciones de claves privadas para el algoritmo de la firma digital Rabin-Williams, lo que permite a atacantes remotos obtener claves privadas a través de un ataque de tiempos.

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).
