Pérdida de memoria en la funcionalidad timezona en PHP antes de v5.3.9, permite a atacantes remotos provocar una denegación de servicio (consumo de memoria) lanzando múltiples llamadas a la función strtotime, que no son manejadas apropiadamente por la caché php_date_parse_tzfile.

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: 7.97 %
Percentil entre todas las CVEs puntuadas: 95
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.
