## Overview

Ghidra through 12.2 contains an uncontrolled memory allocation vulnerability in BinaryField.read() that allows attackers to exhaust heap memory via an unchecked 32-bit length field. Attackers can persuade users to import a crafted GZF packed database file, triggering an OutOfMemoryError in PackedDatabase.open() that aborts the import and denies service.

## Affected

- `ghidra <= 12.2`
