No. The problem were zero-length TLS tickets. It didn't affect connections not using those. It was a server-side change what triggered it. That's why only yahoo accounts were failing. > I did "ldd /bin/evolution | grep tls" and there was no output. > > BTW, I did "ldd /usr/bin/thunderbird" and it said "not a dynamic > executable". That's because that will be a shell script calling the real executable. :-) > It's too bad evolution can't be statically linked. I really prefer > evolution to thunderbird. It wouldn't have helped too much. The bug has been there for years (since version 3.0.0, probably). So unless you were linked to a really old GnuTLS version, a statically linked evolution wouldn't have been free of this bug. Even worse, it would have required to recompile the whole evolution, rather than just updating the GnuTLS library and have that fix all the programs in your computer [that use GnuTLS]. On that first link "with people complaining" that André shared, you could see how it is near resolution by now https://bugs.launchpad.net/ubuntu/+source/evolution/+bug/1876286 ( pending that Ubuntu updates their packages, with the update from https://gitlab.com/gnutls/gnutls/-/issues/997 ) For Scientific Linux, they will need to update GnuTLS or backport the same patch. You should approach your distribution for that. The investigation and work already done on those links should make it quite straightforward for them to fix it, though, as opposed to having to track it down.
