Ghidra before 12.0.3 contains an out-of-memory vulnerability in the rust_demangle function that allocates unbounded output buffers without size limits. Attackers can craft malicious Rust symbol names in binaries to trigger exponential memory allocation, causing process crashes during binary analysis.
