Alpine: multiple synapse packages: security update to 1.93.0-r0
medium Tenable Cloud Security Plugin ID 407310
Description
There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:- Synapse is an open-source Matrix homeserver written and maintained by the Matrix.org Foundation. When
users update their passwords, the new credentials may be briefly held in the server database. While this
doesn't grant the server any added capabilities—it already learns the users' passwords as part of the
authentication process—it does disrupt the expectation that passwords won't be stored in the database. As
a result, these passwords could inadvertently be captured in database backups for a longer duration. These
temporarily stored passwords are automatically erased after a 48-hour window. This issue has been
addressed in version 1.93.0. Users are advised to upgrade. There are no known workarounds for this issue.
(CVE-2023-41335)
- Synapse is an open-source Matrix homeserver written and maintained by the Matrix.org Foundation. Users
were able to forge read receipts for any event (if they knew the room ID and event ID). Note that the
users were not able to view the events, but simply mark it as read. This could be confusing as clients
will show the event as read by the user, even if they are not in the room. This issue has been patched in
version 1.93.0. Users are advised to upgrade. There are no known workarounds for this issue.
