CVE-2026-21676

Estado: AnalizadaAlta (8.8)—

iccDEV provides a set of libraries and tools for working with ICC color management profiles. Versions 2.3.1 and below have a Heap-based Buffer Overflow in its CIccMBB::Validate function which checks tag data validity. This issue is fixed in version 2.3.1.1.

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.

Buffer overflow en función de validación de iccDEV (CWE-122), requiere interacción del usuario (UI:R) para procesar perfil malicioso, permite ejecución de código arbitrario (CVSS C:H I:H A:H).

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.
