Description
Velociraptor's NTFS parsing library mishandles several out of bound and memory exhaustion bugs which may be triggered by maliciously crafted NTFS images.
Typically Velociraptor's NTFS parser is used on live NTFS filesystems, limiting the opportunity of attackers corrupting the filesystem. However, in some applications (e.g. dead disk forensics) Velociraptor may be used on untrusted NTFS image files.
If an attacker is able to inject maliciously corrupted NTFS Volumes they can cause a crash and a Denial of Service.
Problem
CWE-125 Out-of-bounds read
Problem
CWE-789 Memory allocation with excessive size value
Problem
CWE-369 Divide by zero
Required configuration for exposure
This vulnerability is exploitable when ingesting untrusted NTFS volumes and using Velociraptor to parse these in dead disk mode.
Workarounds
The vulnerability results in a crash or memory exhaustion.
