Summary
[none]
Details

In NTFS-3G versions < 2021.8.22, when a specially crafted NTFS attribute is supplied to the function ntfsgetattributevalue, a heap buffer overflow can occur allowing for memory disclosure or denial of service. The vulnerability is caused by an out-of-bound buffer access which can be triggered by mounting a crafted ntfs partition. The root cause is a missing consistency check after reading an MFT record : the "bytesinuse" field should be less than the "bytesallocated" field. When it is not, the parsing of the records proceeds into the wild.
