blurhash_transcoder: prevent out-of-bound reads with <8bpp images (#20388)
The Blurhash library used by Mastodon requires an input encoded as 24
bits raw RGB data. The conversion to raw RGB using Imagemagick did not
previously specify the desired bit depth. In some situations, this leads
Imagemagick to output in a pixel format using less bpp than expected.
This then manifested as segfaults of the Sidekiq process due to
out-of-bounds read, or potentially a (highly noisy) memory infoleak.

Fixes #19235.

Mastodon

GitHub release Build Status Code Climate Crowdin Docker Pulls

Mastodon is a free, open-source social network server based on ActivityPub where users can follow friends and discover new ones. On Mastodon, users can publish anything they want: links, pictures, text, video. All Mastodon servers are interoperable as a federated network (users on one server can seamlessly communicate with users from another one, including non-Mastodon software that implements ActivityPub)!

Features

No vendor lock-in: Fully interoperable with any conforming platform

It doesn't have to be Mastodon; whatever implements ActivityPub is part of the social network! Learn more

Real-time, chronological timeline updates

Updates of people you're following appear in real-time in the UI via WebSockets. There's a firehose view as well!

Media attachments like images and short videos

Upload and view images and WebM/MP4 videos attached to the updates. Videos with no audio track are treated like GIFs; normal videos loop continuously!

Safety and moderation tools

Mastodon includes private posts, locked accounts, phrase filtering, muting, blocking and all sorts of other features, along with a reporting and moderation system. Learn more

OAuth2 and a straightforward REST API

Mastodon acts as an OAuth2 provider, so 3rd party apps can use the REST and Streaming APIs. This results in a rich app ecosystem with a lot of choices!

Deployment

Tech stack:

  • Ruby on Rails powers the REST API and other web pages
  • React.js and Redux are used for the dynamic parts of the interface
  • Node.js powers the streaming API

Requirements:

  • PostgreSQL 9.5+
  • Redis 4+
  • Ruby 2.6+
  • Node.js 14+

The repository includes deployment configurations for Docker and docker-compose as well as specific platforms like Heroku, Scalingo, and Nanobox. The standalone installation guide is available in the documentation.

A Vagrant configuration is included for development purposes. To use it, complete following steps:

  • Install Vagrant and Virtualbox
  • Install the vagrant-hostsupdater plugin: vagrant plugin install vagrant-hostsupdater
  • Run vagrant up
  • Run vagrant ssh -c "cd /vagrant && foreman start"
  • Open http://mastodon.local in your browser

Contributing

Mastodon is free, open-source software licensed under AGPLv3.
