Description
The Sleuth Kit through 4.15.0 contains a heap out-of-bounds read vulnerability in hfs_load_extended_attrs() in tsk/fs/hfs.c that reads the decmpfs header without checking attribute length. Attackers can supply a crafted HFS+ image with a com.apple.decmpfs attr_size of 1 to 15 to read past the allocation and crash analysis tools like istat or icat.
