Description

Ghidra before 12.2 contains a resource allocation without limits vulnerability in ExtensionUtils.unzipToInstallationFolder() that extracts every extension ZIP entry without limiting file count. Attackers who persuade a user to install a crafted extension archive with many files can exhaust filesystem inodes, causing project writes and other processes to fail.
