Fedora 37 : matrix-synapse (2023-eb65439ec0)

medium Nessus Plugin ID 177094

Language:

Synopsis

The remote Fedora host is missing one or more security updates.

Description

The remote Fedora 37 host has a package installed that is affected by a vulnerability as referenced in the FEDORA-2023-eb65439ec0 advisory.

 - Synapse is an open-source Matrix homeserver written and maintained by the Matrix.org Foundation. The Matrix Federation API allows remote homeservers to request the authorization events in a room. This is necessary so that a homeserver receiving some events can validate that those events are legitimate and permitted in their room. However, in versions of Synapse up to and including 1.68.0, a Synapse homeserver answering a query for authorization events does not sufficiently check that the requesting server should be able to access them. The issue was patched in Synapse 1.69.0. Homeserver administrators are advised to upgrade. (CVE-2022-39335)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected matrix-synapse package.
