CVE-2016-7134

Estado: ModificadaCrítica (9.8)—

ext/curl/interface.c en PHP 7.x en versiones anteriores a 7.0.10 no evita un desbordamiento de entero en libcurl, lo que permite a atacantes remotos provocar una denegación de servicio (error de localización y desbordamiento de búfer basado en memoria dinámica) o tener otro posible impacto no especificado a través de una cadena larga que no es manejada correctamente en una llamada curl_escape.

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).
