CVE-2020-10233Public exploit

CLI crash via undersized NTFS update-array guard

Published Mar 8, 2020 · Updated Aug 4, 2024

Heap-based buffer over-read in The Sleuth Kit 4.8.0 and earlier allows attackers to crash fls by processing a crafted NTFS image. ntfs_dinode_lookup in tsk/fs/ntfs.c validates only the two-byte ntfs_upd structure at the update-sequence offset, ignoring the remaining update array before reading it. The attacker must cause an affected command-line tool to parse the image; the demonstrated consequence is an AddressSanitizer-detected abort, not code execution.
