4Description
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.
Analysis
Out-of-bounds read in The Sleuth Kit through 4.14.0 allows local attackers with user interaction to disclose sensitive information via a crafted ISO9660 image, exploiting the parse_susp() function's failure to validate field lengths before copying SUSP extension data into stack buffers. The vulnerability can also trigger infinite parsing loops with malformed zero-length SUSP entries. …
