= CVE-2020-8492 Speed Tests

CVE-2020-8492 describes a DOS opportunity for malicious servers responding to requests from the Python built-in urllib library.

A malicious server can send up to 65,509 additional commas in the WWW-Authenticate header, which triggers an O(2**n) evaluation of a regular expression.

This folder contains a sample malicious server (in Python 3), and sample vulnerable clients (in Python 2 and 3)

This patches WeakSet.add to prevent it having a spurious error if a weak ref goes away between calling this function and adding it
This is done analogously to the patch in https://github.com/python/cpython/commit/f8de3fea1280d55377d40c6e04b64114f9da2fa6:
  "#10360: catch TypeError in WeakSet.__contains__, just like WeakKeyDictionary does."
See https://bugs.python.org/issue10360 for infomration on that

"""This is a script for internal use when doing large mail migrations with mbsync
See http://isync.sourceforge.net/mbsync.html for more information on the product
If IMAP disconnects occur on a large mailbox, the internal .journal file that tracks progress
 can grow very large in size, though much of the information is not needed
This script can be used to reduce the file in size

NB: This should be used with caution, and never while mbsync is running
It does not replace the file, but can be used to produce a new journal file,
