Erik Johnston 320e8c8064 Synapse 1.23.1 (2020-12-09)
===========================
 
 Due to the two security issues highlighted below, server administrators are
 encouraged to update Synapse. We are not aware of these vulnerabilities being
 exploited in the wild.
 
 Security advisory
 -----------------
 
 The following issues are fixed in v1.23.1 and v1.24.0.
 
 - There is a denial of service attack
   ([CVE-2020-26257](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-26257))
   against the federation APIs in which future events will not be correctly sent
   to other servers over federation. This affects all servers that participate in
   open federation. (Fixed in [#8776](https://github.com/matrix-org/synapse/pull/8776)).
 
 - Synapse may be affected by OpenSSL
   [CVE-2020-1971](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-1971).
   Synapse administrators should ensure that they have the latest versions of
   the cryptography Python package installed.
 
 To upgrade Synapse along with the cryptography package:
 
 * Administrators using the [`matrix.org` Docker
   image](https://hub.docker.com/r/matrixdotorg/synapse/) or the [Debian/Ubuntu
   packages from
   `matrix.org`](https://github.com/matrix-org/synapse/blob/master/INSTALL.md#matrixorg-packages)
   should ensure that they have version 1.24.0 or 1.23.1 installed: these images include
   the updated packages.
 * Administrators who have [installed Synapse from
   source](https://github.com/matrix-org/synapse/blob/master/INSTALL.md#installing-from-source)
   should upgrade the cryptography package within their virtualenv by running:
   ```sh
   <path_to_virtualenv>/bin/pip install 'cryptography>=3.3'
   ```
 * Administrators who have installed Synapse from distribution packages should
   consult the information from their distributions.
 
 Bugfixes
 --------
 
 - Fix a bug in some federation APIs which could lead to unexpected behaviour if different parameters were set in the URI and the request body. ([\#8776](https://github.com/matrix-org/synapse/issues/8776))
 
 Internal Changes
 ----------------
 
 - Add a maximum version for pysaml2 on Python 3.5. ([\#8898](https://github.com/matrix-org/synapse/issues/8898))
