Technical details
The vulnerability is an uncontrolled memory allocation flaw in the BinaryField.read() method that fails to validate a 32-bit length field before allocating heap memory. An attacker can craft a GZF-packed database file with an oversized length value to trigger an OutOfMemoryError when PackedDatabase.open() attempts to process it, resulting in application denial of service. The vulnerability requires user interaction (importing a malicious file) and affects Ghidra through version 12.2.
