Description
The Sleuth Kit through 4.14.0 contains an out-of-bounds read vulnerability in the APFS filesystem keybag parser where the wrapped_key_parser class follows attacker-controlled length fields without bounds checking, causing heap reads past the allocated buffer. An attacker can craft a malicious APFS disk image that triggers information disclosure or crashes when processed by any Sleuth Kit tool that parses APFS volumes.
