Description

When Neethi fetches a remote policy reference, it only limits the time per read, not the whole transfer, so a server that trickles bytes slowly can keep the fetch alive indefinitely and tie up the calling thread (denial of service). Users are recommended to upgrade to version 3.2.4, which fixes this issue.
