Subject: openvpn: Segfault after 2.5.1-3+deb11u3 upgrade Package: openvpn X-Debbugs-Cc: [email protected] Version: 2.5.1-3+deb11u3 Severity: normal
Dear Maintainer, Upgrading openvpn from 2.5.1-3 to 2.5.1-3+deb11u3 lead to segfault crashes. I'm seeing TLS timeouts too in the logs but I'm unsure if those are correlated.

Rolling back the openvpn version fixed the issue. I understand this version of Debian is not supported anymore, and this will likely get no fix. But I thought about reporting it to document it for others.
