      "value": "Velociraptor's NTFS parsing library mishandles several out of bound and memory exhaustion bugs which may be triggered by maliciously crafted NTFS images.\n\nTypically Velociraptor's NTFS parser is used on live NTFS filesystems, limiting the opportunity of attackers corrupting the filesystem. However, in some applications (e.g.  dead disk forensics https://docs.velociraptor.app/docs/forensic/deaddisk/ ) Velociraptor may be used on untrusted NTFS image files. \n\nIf an attacker is able to inject maliciously corrupted NTFS Volumes they can cause a crash and a Denial of Service."

      "value": "La biblioteca de análisis NTFS de Velociraptor maneja incorrectamente varios errores de desbordamiento de límites y agotamiento de memoria que pueden ser activados por imágenes NTFS creadas con fines maliciosos.\n\nTípicamente, el analizador NTFS de Velociraptor se utiliza en sistemas de archivos NTFS en vivo, lo que limita la oportunidad de que los atacantes corrompan el sistema de archivos. Sin embargo, en algunas aplicaciones (por ejemplo, análisis forense de discos muertos https://docs.velociraptor.app/docs/forensic/deaddisk/ ), Velociraptor puede ser utilizado en archivos de imagen NTFS no confiables.\n\nSi un atacante es capaz de inyectar Volúmenes NTFS corrompidos maliciosamente, pueden causar un fallo y una denegación de servicio."
