strtod.c, tal como se utiliza en la función zend_strtod en PHP v5.2 anterior de v5.2.17 y v5.3 anterior de v5.3.5, y otros productos, permite a atacantes dependientes del contexto provocar una denegación de servicio (bucle infinito) a través de un cierto valor de punto flotante en notación científica, que no se manipula correctamente en los registros FPU x87.

CVSS

Puntuación base: 5
Versión: 2.0
Vector: AV:N/AC:L/Au:N/C:N/I:N/A:P

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 15 %
Percentil entre todas las CVEs puntuadas: 97
Fecha de la puntuación: 21/10/2026

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).

Exploits públicos

Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.
