# Ghidra: crafted packed stream truncates lengths, crashes decompiler or injects attributes

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

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Run `ghidra --version` or check the Ghidra install folder for the version number, and see whether it is below `12.2`
- Check whether the team opens untrusted .sla or packed-format files in Ghidra

## Fix

- Upgrade Ghidra to `12.2` or later
- Only open .sla and packed-format files from trusted sources until upgraded

## From the sources

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.
