[Bug 1848709] Re: implementation is unusably old and contains significant security problems
> > but Debian does not include matrix-synapse in Debian Stable releases. > > [citation needed] https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1036954, https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1036806#30 You're right that it's not *policy*. But, for now at least, Debian are not including matrix-synapse in their stable releases. > And the bug originally reported here was against the version of the package in bionic, a year and a half after bionic released. That security vulnerabilities were discovered in a package over the life cycle of a stable release is also not a reason for us to remove it. Is it not? Ubuntu claims to support its LTS releases for five years; I'd argue pretty strongly that the expectation is that security vulnerabilities, at least, are patched for those five years. If you're unable to do that (and I appreciate that it's a lot of work), better not to ship the package in the first place. Ubuntu users are much better served by the upstream packages. To be clear, this problem was originally reported against Bionic, but it's true of every Ubuntu release before and since. CVE-2024-31208 is a High severity CVE which affects all current Ubuntu releases. CVE-2023-45129 affects the version of matrix-synapse in Mantic and Noble. The version in Jammy is, frankly, prehistoric. > But https://ubuntu.com/security/cves?q==matrix- synapse=== also shows none of these CVEs are scored above 'medium' priority. True, but doesn't that rather reflect lack of triage, than any actual severity? ** Bug watch added: Debian Bug tracker #1036954 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1036954 ** CVE added: https://cve.mitre.org/cgi-bin/cvename.cgi?name=2023-45129 ** CVE added: https://cve.mitre.org/cgi-bin/cvename.cgi?name=2024-31208 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1848709 Title: implementation is unusably old and contains significant security problems To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/matrix-synapse/+bug/1848709/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Ok, I reproduced this on a rebuild of 6.5.0-34 with CONFIG_PROVE_LOCKING. Here are some relevant-looking bits of the logs. It looks like the wireplumber process and the usb_disconnect process have deadlocked?

> And this call trace looks is related to current issue, I guess snd_power_ref_and_wait was waiting for snd_card_disconnect which wakes up power_sleep at the end of the code, but snd_card_disconnect -> snd_device_disconnect_all -> snd_pcm_dev_disconnect was blocked for some reason. Yes, interesting. Good spot. > Looks suspend/resume can be completed sometimes. Yes. I think what causes the problem is when I disconnect from my USB dock. After that, I can't suspend until I reboot.

Public bug reported: The versions of matrix-synapse in 18.04 and 18.10 are sufficiently old that they will be unable to communicate with any other Matrix servers. They also contain a number of known security problems, including CVE-2019-5885 [1].
