I installed the package available in bionic-proposed as you can see below: root@openldap-bionic-sru:~# apt policy slapd slapd: Installed: 2.4.45+dfsg-1ubuntu1.4 Candidate: 2.4.45+dfsg-1ubuntu1.4 Version table: *** 2.4.45+dfsg-1ubuntu1.4 500 500 http://archive.ubuntu.com/ubuntu bionic-proposed/main amd64 Packages 100 /var/lib/dpkg/status 2.4.45+dfsg-1ubuntu1.3 500 500 http://archive.ubuntu.com/ubuntu bionic-updates/main amd64 Packages 500 http://security.ubuntu.com/ubuntu bionic-security/main amd64 Packages 2.4.45+dfsg-1ubuntu1 500 500 http://archive.ubuntu.com/ubuntu bionic/main amd64 Packages
And after executing the steps presented in the Test case section, the slapd process did not die: root@openldap-bionic-sru:~# ps aux | grep slapd openldap 1029 0.0 4.5 2106104 730124 ?

Moreover, there is no sign of crash in the syslog output nor a crash file in /var/crash: root@openldap-bionic-sru:~# cat /var/log/syslog | grep filter_free root@openldap-bionic-sru:~# ls /var/crash/ | grep slapd ** Tags removed: verification-needed-bionic -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1838370 Title: slapd segfault on filter parse error To manage notifications about this bug go to: https://bugs.launchpad.net/openldap/+bug/1838370/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
