Descriptions
A crafted NTFS image with an unallocated bitmap can lead to a endless recursive function call chain (starting from ntfs_attr_pwrite), causing stack consumption in NTFS-3G < 2021.8.22.
Una imagen NTFS diseñada con un mapa de bits sin asignar puede conllevar a una cadena interminable de llamadas a funciones recursivas (empezando por ntfs_attr_pwrite), causando un consumo de la pila 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 system availability.
