Ghidra before 12.2 contains a numeric truncation vulnerability in PackedDecode::skipAttribute and skipAttributeRemaining in marshal.cc that stores 64-bit string lengths in 32-bit variables. Attackers can supply a crafted packed stream, such as a malicious .sla file, to inject attributes into the decompiler's input or crash the decompiler process.
