Ghidra before 12.2 contains an improper handling of highly compressed data vulnerability in ExtensionUtils.unzipToInstallationFolder() that allows attackers to exhaust disk space. Attackers can persuade users to install a crafted zip bomb extension archive that expands without size limits, causing later writes by Ghidra and other applications to fail.
