Details

It was discovered that NTFS-3G incorrectly handled the ntfsck tool. If a
user or automated system were tricked into using ntfsck on a specially
crafted disk image, a remote attacker could possibly use this issue to
execute arbitrary code. (CVE-2021-46790)

Roman Fiedler discovered that NTFS-3G incorrectly handled certain return
codes. A local attacker could possibly use this issue to intercept
protocol traffic between FUSE and the kernel. (CVE-2022-30783)

It was discovered that NTFS-3G incorrectly handled certain NTFS disk
images. If a user or automated system were tricked into mounting a
