Ghidra 10.3 before 12.2 contains an improper handling of highly compressed data vulnerability in ThemeReader.processIconFile() that fails to limit decompressed size or compression ratio. Attackers can persuade a user to import a crafted theme ZIP whose icon entries expand to fill the host filesystem, causing later writes to fail.
