Estado: ModificadaMedia (6.5)—

** EN DISPUTA ** La función libfsclfs_block_read en libfsclfs_block.c en libfsntfs en versiones anteriores al 25/07/2018 permite que atacantes remotos provoquen una sobrelectura de búfer basada en memoria dinámica (heap) mediante un archivo clfs manipulado. NOTA: el fabricante ha disputado esto, tal y como se describe en los comentarios de problemas de GitHub.

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).
