CVE-2019-11048

Estado: ModificadaMedia (5.3)—

En PHP versiones 7.2.x por debajo de 7.2.31, versiones 7.3.x por debajo de 7.3.18 y 7.4.x por debajo de 7.4.6, cuando son permitidas las descargas de archivos HTTP, el suministro de nombres de archivo o de campo demasiado largos podría conllevar al motor PHP a intentar asignar un almacenamiento de memoria sobredimensionado, alcanzar el límite de memoria y detener el procesamiento de la petición, sin limpiar los archivos temporales creados por la petición de descarga. Esto podría conllevar a la acumulación de archivos temporales sin limpiar que agotan el espacio de disco en el servidor de destino.

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).
