The Sleuth Kit through 4.15.0 contains a NULL pointer dereference vulnerability in decmpfs decompress lzvn attr() that allows attackers to crash the tool by supplying a crafted HFS+ image. Attackers can set a huge uncompressed size in an LZVN inline com.apple.decmpfs attribute so allocation fails and the decoder writes through NULL, causing denial of service.
