+Subject: [PATCH] src/murmur/Server.cpp: implement workaround for critical
+ QSslSocket issue
+
+A severe bug was introduced in qt/qtbase at 93a803a6de27d9eb57931c431b5f3d074914f693: q_SSL_shutdown() causes Qt to emit "error()" from unrelated QSslSocket(s), in addition to the correct one.
+
+The issue causes Server::connectionClosed() to disconnect random authenticated clients.
+
+The workaround consists in ignoring a specific OpenSSL error:
+"Error while reading: error:140E0197:SSL routines:SSL_shutdown:shutdown while in init [20]"
+
+Definitely not ideal, but it fixes a critical vulnerability. Details on how to trigger it are deliberately omitted.
