Summary

Ghidra from 10.3 before 12.2 fails to limit the decompressed size or compression ratio of data in ThemeReader.processIconFile(), which is CWE-409. An attacker can persuade a user to import a crafted theme ZIP whose icon entries expand until they fill the host filesystem, so later writes fail. The attack requires user interaction and local access, and it affects availability.
