Threats affecting pkg:github/The Sleuth Kit

The Sleuth Kit up to version 4.15.0 has a NULL pointer dereference vulnerability in the decmpfs_decompress_lzvn_attr() function. This flaw can be triggered by supplying a crafted HFS+ image with a specially manipulated LZVN inline com.apple.decmpfs attribute that sets an excessively large uncompressed size. The vulnerability causes a denial of service by crashing the tool due to a failed allocation and subsequent NULL pointer write.

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.
