The vulnerabilties are fixed in Twisted 20.3.0, and are +described in +[CVE-2020-10108](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-10108) +and +[CVE-2020-10109](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-10109). +For a good introduction to this class of request-smuggling attacks, see +https://portswigger.net/research/http-desync-attacks-request-smuggling-reborn. + +We are not aware of these vulnerabilities being exploited in the wild, and +do not believe that they are exploitable with current versions of any reverse +proxies. Nevertheless, we recommend that all Synapse administrators ensure that +they have the latest versions of the Twisted library to ensure that their +installation remains secure. + +* 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 1.12.0 installed: these images include + Twisted 20.3.0. +* Administrators who have [installed Synapse from + source](https://github.com/matrix-org/synapse/blob/master/INSTALL.md#installing-from-source) + should upgrade Twisted within their virtualenv by running: + ```sh + <path_to_virtualenv>/bin/pip install 'Twisted>=20.3.0' + ``` +* Administrators who have installed Synapse from distribution packages should + consult the information from their distributions. + +The `matrix.org` Synapse instance was not vulnerable to these vulnerabilities. + +Advance notice of change to the default `git` branch for Synapse +---------------------------------------------------------------- + +Currently, the default `git` branch for Synapse is `master`, which tracks the +latest release. + +After the release of Synapse 1.13.0, we intend to change this default to +`develop`, which is the development tip. This is more consistent with common +practice and modern `git` usage. + +Although we try to keep `develop` in a stable state, there may be occasions +where regressions creep in. Developers and distributors who have scripts which +run builds using the default branch of `Synapse` should therefore consider +pinning their scripts to `master`. + + +Synapse 1.12.0rc1 (2020-03-19) +============================== + +Features +-------- + +- Changes related to room alias management ([MSC2432](https://github.com/matrix-org/matrix-doc/pull/2432)): + - Publishing/removing a room from the room directory now requires the user to have a power level capable of modifying the canonical alias, instead of the room aliases.
