CVE-2017-14749

Estado: ModificadaAlta (7.8)—

La versión 1.0 de JerryScript permite que los atacantes remotos provoquen una denegación de servicio (corrupción de la memoria dinámica "heap" jmem_heap_alloc_block_internal) o, posiblemente, que ejecuten código arbitrario mediante un archivo .js manipulado. Esto se debe a que los caracteres \ no reconocidos provocan caracteres 0x00 incorrectos en los datos de bytecode.literal.

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).
