Note that if you use the lower level Zip::InputStream interface, rubyzip does not check the entry sizes. If you need to extract zip files that report incorrect uncompressed sizes and you really trust them not too be too large, you can disable this setting with Zip. file? raise ' Too many extracted files ' if num_files > MAX_FILES raise ' File too large when extracted ' if entry. each do | entry | num_files += 1 if entry.

For example, if your application supports processing up to 100 files at once, each up to 10MiB, your zip extraction code might look like: MAX_FILE_SIZE = 10 * 1024 ** 2 # 10MiB Before extracting an entry, you should check that its size is in the range you expect. This is to help you protect your application against zip bombs.
