Title
Ghidra 10.2 < 12.1 - Denial of Service via Circular Reference in Mach-O Export Trie Parser
Summary
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.
Severity ?
5.5 (Medium)
