Descriptions

A crafted NTFS image can trigger an out-of-bounds access, caused by an unsanitized attribute length in ntfs_inode_lookup_by_name, in NTFS-3G < 2021.8.22.

Una imagen NTFS diseñada puede desencadenar un acceso fuera de límites, causado por una longitud de atributo no saneada en la función ntfs_inode_lookup_by_name, en NTFS-3G versiones anteriores a 2021.8.22

The ntfs3g package is susceptible to a heap overflow on crafted input. When processing an NTFS image, proper bounds checking was not enforced leading to this software flaw. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.
