Alpine: multiple synapse packages: security update to 1.93.0-r0 (deprecated)

medium Tenable Cloud Security Plugin ID 401390

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- Synapse is an open-source Matrix homeserver written and maintained by the Matrix.org Foundation. Prior to
version 1.94.0, a malicious server ACL event can impact performance temporarily or permanently leading to
a persistent denial of service. Homeservers running on a closed federation (which presumably do not need
to use server ACLs) are not affected. Server administrators are advised to upgrade to Synapse 1.94.0 or
later. As a workaround, rooms with malicious server ACL events can be purged and blocked using the admin
API. (CVE-2023-45129)
