Description

Ghidra before 12.1.3 contains an uncontrolled resource consumption vulnerability in the PDB parser that allows attackers to terminate the Ghidra process by supplying a crafted PDB file with an oversized parameters section. The AbstractPdb deserialization routine reads all remaining parameters into an unbounded list, causing uncontrolled heap growth that triggers an OutOfMemoryError which bypasses exception handling and crashes the application.
