CVE-2018-16323

Estado: ModificadaMedia (6.5)—💥 Exploit

ReadXBMImage en coders/xbm.c en ImageMagick en versiones anteriores a la 7.0.8-9 deja los datos sin inicializar al procesar un archivo XBM que tiene un valor de pixel negativo. Si el código afectado se emplea como biblioteca cargada en un proceso que incluye información sensible, esa información a veces puede filtrarse mediante los datos de imagen.

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).

💥 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.

⚠️ Las pruebas de concepto de GitHub no están verificadas: algunas son falsas o contienen malware. No las ejecute nunca fuera de un laboratorio aislado.
