Low risk3th percentile - higher than 3% of all known CVEs
Summary
The Sleuth Kit through 4.14.0 contains an out-of-bounds read vulnerability in the ISO9660 filesystem parser where the parse_susp() function trusts len_id, len_des, and len_src fields from the disk image to memcpy data into a stack buffer without verifying that the source data falls within the parsed SUSP block. An attacker can craft a malicious ISO image that causes reads past the end of the SUSP data buffer, and a zero-length SUSP entry can trigger an infinite parsing loop.
Risk Assessment
The vulnerability may lead to disclosure of sensitive data or system crashes during forensic analysis of ISO images.
Recommendation
Update The Sleuth Kit to version 4.14.1 or later if available; otherwise, avoid processing untrusted ISO images.
