  "details" : [ "A crafted NTFS image can cause an integer overflow in memmove, leading to a heap-based buffer overflow in the function ntfs_attr_record_resize, in NTFS-3G < 2021.8.22.", "The ntfs3g package is susceptible to an input validation flaw. A crafted NTFS image with invalid values could trigger an improper check. This incorrect check causes an integer overflow which then leads to a heap overflow. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability." ],
