CVE-2025-43962

Estado: ModificadaCrítica (9.1)—

In LibRaw before 0.21.4, phase_one_correct in decoders/load_mfbacks.cpp has out-of-bounds reads for tag 0x412 processing, related to large w0 or w1 values or the frac and mult calculations.

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.

Lectura fuera de límites en procesamiento de etiquetas TIFF en LibRaw expuesto por red sin privilegios (AV:N/PR:N); impacto en confidencialidad (C:H) sugiere acceso a datos en memoria.

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.
