Hi all We are using postfix smtp_tls_policy_maps with a MySQL lookup table. This setup worked good until we upgraded the following packages today because of CVE-2015-7547 (its a debian wheezy, upgraded as usual via apt-get upgrade): libc-bin:amd64 (2.13-38+deb7u7, 2.13-38+deb7u10), libc6-dev:amd64 (2.13-38+deb7u7, 2.13-38+deb7u10), libc-dev-bin:amd64 (2.13-38+deb7u7, 2.13-38+deb7u10), libc6:amd64 (2.13-38+deb7u7, 2.13-38+deb7u10), libk5crypto3:amd64 (1.10.1+dfsg-5+deb7u2, 1.10.1+dfsg-5+deb7u7), dnsutils:amd64 (9.8.4.dfsg.P1-6+nmu2+deb7u3, 9.8.4.dfsg.P1-6+nmu2+deb7u9), libmysqlclient18:amd64 (5.5.41-0+wheezy1, 5.5.47-0+deb7u1), libssl-dev:amd64 (1.0.1e-2+deb7u15, 1.0.1e-2+deb7u19), openssl:amd64 (1.0.1e-2+deb7u15, 1.0.1e-2+deb7u19), mysql-common:amd64 (5.5.41-0+wheezy1, 5.5.47-0+deb7u1), mysql-client-5.5:amd64 (5.5.41-0+wheezy1, 5.5.47-0+deb7u1), libssl1.0.0:amd64 (1.0.1e-2+deb7u15, 1.0.1e-2+deb7u19) (plus some other packages definitely not related to postifx/mysql) so mainly libc and mysql-client was upgraded. postfix-packages where left untouched. Now smtp is crashing right after it tries to connect to the mysql-host: Feb 24 15:20:33 sig01 postfix/smtp[8796]: dict_mysql_get_active: attempting to connect to host mysql.host.tld Feb 24 15:20:33 sig01 postfix/qmgr[6794]: warning: private/smtp socket: malformed response Feb 24 15:20:33 sig01 postfix/qmgr[6794]: warning: transport smtp failure -- see a previous warning/fatal/panic logfile record for the problem description Feb 24 15:20:33 sig01 postfix/master[6785]: warning: process /usr/lib/postfix/smtp pid 8796 killed by signal 11 Mails remain in queue with: status=deferred (unknown mail transport error) Outside of postfix I am able to connect to the mysql server (from the affected machine) without any problems. Anyone here with an idea how to fix this? Regards Christian
