CVE-2026-46602

Estado: AplazadaAlta (7.5)—

The TIFF decoder does not set a limit on the size of tiles in tiled images, permitting a malicious or corrupt image containing a very large tile to cause unbounded memory consumption.

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).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

CVSS AV:N/PR:N/UI:N sugiere T1190 (aplicación expuesta en red). Decodificador TIFF malformado → consumo ilimitado de memoria → DoS aplicación (T1499.004).

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
