Ghidra before 12.1.1 contains an uncontrolled memory allocation vulnerability in the Mach-O binary parser that allows attackers to cause denial of service. An attacker can supply a crafted Mach-O binary with an arbitrarily large ncmds load command count value, forcing the parser to allocate excessive heap memory without validating file size, crashing the Ghidra JVM.
