CVE-2026-21491

Estado: AnalizadaAlta (7.1)—

iccDEV provides a set of libraries and tools that allow for the interaction, manipulation, and application of International Color Consortium (ICC) color management profiles. A vulnerability present in versions prior to 2.3.1.2 affects users of the iccDEV library who process ICC color profiles. It results in unicode buffer overflow in `CIccTagTextDescription`. Version 2.3.1.2 contains a patch. No known workarounds are available.

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.

Vector CVSS con UI:R (requiere interacción del usuario, abrir perfil ICC preparado) indica T1203. Buffer overflow en procesamiento de archivos permite ejecución de código arbitrario (T1059).

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.
