Description

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.
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.
