In a serial orparallel manner.If one of the servers hosting the contents has been breached and the contentsof the specific file on that server is replaced with a modified payload, curlshould detect this when the hash of the file mismatches after a completeddownload.

This is not done, and instead such a hash mismatch is onlymentioned in text and the potentially malicious content is kept in the file ondisk."
