Summary

Ghidra before 12.2 contains a flaw in ExtensionUtils.unzipToInstallationFolder() that mishandles highly compressed data (CWE-409). An attacker who persuades a user to install a crafted zip bomb extension archive can exhaust disk space, because the archive expands without size limits. The attack requires user interaction, and later writes by Ghidra and other applications then fail.
