It is indeed a GnuTLS bug. It can be reproduced using only gnutls-cli: gnutls-cli pop.verizon.net -p 995 gnutls-cli imap.aol.com -p 993
I can reproduce it with gnutls28 (jessie), but not gnutls26 (wheezy). Those covered the jump from 2.2.6 to 3.0.0, where they changed from libgcrypt to nettle, so not that strange they have different behavior. The problem was not added by a recent Ubuntu update. It's a bug which was present in the past, and that only now is being exposed by whatever Yahoo changed. Gmail servers doesn't expose it. Thunderbird is not affected since it uses NSS, not GnuTLS. As a workaround, affected users could run on a separate terminal a command such as socat tcp-listen:9950,fork openssl-connect:pop.verizon.net:995,capath=/etc/ssl/certs and then configure evolution to connect to localhost:9950 (without TLS) instead of pop.verizon.net:995. This way, the actual encryption is performed by socat... using openssl. ** Also affects: gnutls28 (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1876286 Title: Evolution reports "Error performing TLS handshake: Internal error in memory allocation."
