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.
* Fix error-prone SQL queries in Account search
While this code seems to not present an actual vulnerability, one could
easily be introduced by mistake due to how the query is built.
This PR parameterises the `to_tsquery` input to make the query more robust.
* Harden code for Status#tagged_with_all and Status#tagged_with_none
Those two scopes aren't used in a way that could be vulnerable to an SQL
injection, but keeping them unchanged might be a hazard.
* Remove unneeded spaces surrounding tsquery term
* Please CodeClimate
* Move advanced_search_for SQL template to its own function
This avoids one level of indentation while making clearer that the SQL template
isn't build from all the dynamic parameters of advanced_search_for.
* Add tests covering tagged_with, tagged_with_all and tagged_with_none
* Rewrite tagged_with_none to avoid multiple joins and make it more robust
* Remove obsolete brakeman warnings
* Revert "Remove unneeded spaces surrounding tsquery term"
The two queries are not strictly equivalent.
This reverts commit 86f16c537e06c6ba4a8b250f25dcce9f049023ff.
* Fix followers synchronization mechanism not working when URI has empty path
To my knowledge, there is no current implementation on the fediverse
that can use bare domains (e.g., actor is at https://example.org instead of
something like https://example.org/actor) that also plans to support the
followers synchronization mechanism. However, Mastodon's current implementation
would exclude such accounts from followers list.
Also adds tests and rename them to reflect the proper method names.
* Move url prefix regexp to its own constant
* Build container image by GitHub Actions
* Trigger docker build only pushed to main branch
* Tweak tagging imgae
- "edge" is the main branch
- "latest" is the tagged latest release
Some bundle options are saved as global user config and not project local.
Specially, `deployment` must be saved as local config to be run on copied environment
* Fix error when suspending user with an already-existing canonical email block
Fixes#17033
While attempting to create a `CanonicalEmailBlock` with an existing hash would
raise an `ActiveRecord::RecordNotUnique` error, this being done within a
transaction would cancel the whole transaction. For this reason, checking for
uniqueness in Rails would query the database within the transaction and avoid
invalidating the whole transaction for this reason.
A race condition is still possible, where multiple accounts sharing a canonical
email would be blocked in concurrent transactions, in which only one would
succeed, but that is way less likely to happen that the current issue, and can
always be retried after the first failure, unlike the current situation.
* Add tests
For some reason, some misconfigured servers return an empty document when
queried over webfinger. Since an empty document does not lead to a parse
error, the error is not caught properly and triggers uncaught exceptions
later on.
This PR fixes that by immediately erroring out with `Webfinger::Error` on
getting an empty response.
Under certain conditions, files fetched from remotes trigger an error when
being uploaded using OpenStack Swift. This is because in some cases, the
remote server will not return a content-length, so our ResponseWithLimitAdapter
will hold a `nil` value for `#size`, which will lead to an invalid value
for the Content-Length header of the Swift API call.
This commit fixes that by taking the size from the actually-downloaded file
size rather than the upstream-provided Content-Length header value.
Fixes#16515
Not using a router object somehow made `this.history` lag behind the real
browser history whenever pushing a new history item in `replyCompose`.
Not using the context-provided router in this case was an oversight made
when porting glitch-soc changes in #16499.
