1) Out-of-bounds read (CVE-ID: CVE-2019-19648)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary condition in the "macho_parse_file" functionality in "macho/macho.c" file when "command_size" may be inconsistent with the real size. A remote attacker can send a specially crafted MachO file, trigger out-of-bounds read error and cause a denial of service condition on the target system.
