[Kolab-devel] Erlang security update breaks guam on Debian 10

[Christoph Erhardt]

Hi all,

if my understanding is correct, CVE-2022-37026 allows an authentication bypass 
by clients when using certificate-based authentication, while 'normal' user/
password-based authentication is not affected.

If that is indeed the case, then I believe our quick fix doesn't entail an 
immediate risk to Guam users.

Nevertheless, I do feel somewhat strongly about doing things the right way. In 
our case this would mean:
1. Make OBS pull the latest Debian 10 packages, including erlang-base.
2. Revert the patch that enables ERTS bundling for Guam.
3. Rebuild Guam.

I'm happy to take care of steps 2 and 3, but step 1 needs to be done by an OBS 
admin. Christian? Jeroen?

Best,
Christoph
