Technical description

Ghidra 10.2 before 12.1 contains an uncontrolled resource consumption vulnerability in ExportTrie.parseTrie() that lacks cycle detection when traversing Mach-O binary export tries. A crafted Mach-O binary with circular references in the export trie causes unbounded queue growth and exponential string concatenation, triggering OutOfMemoryError that crashes the entire JVM and loses all unsaved work.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
