Created attachment 1740171 [details] pkgdiff report between openldap-2.4.46-11.el8_1 and openldap-2.4.46-15.el8 Created attachment 1740171 [details] pkgdiff report between openldap-2.4.46-11.el8_1 and openldap-2.4.46-15.el8 Description of problem: We are running an installation of apache httpd (2.4.46) where we compile it and bundle compiled versions of openssl (1.1.1i) and modsecurity (2.9.3). It has been running fine in several different environments on both RHEL 7 and 8 as well as CentOS 7 and 8. The other day, it suddenly started failing with the following error message when loading modsecurity: httpd: Syntax error on line 251 of httpd.conf: Cannot load modules/mod_security2.so into server: /lib64/libldap-2.4.so.2: undefined symbol: EVP_md2, version OPENSSL_1_1_0 Our investigations shows that this started happening when openldap was bumped from openldap-2.4.46-11 to openldap-2.4.46-15 during a regular system update. I'm not competent enough in these matters to say if this is a bug with the release of the package or not, just hoping that you might be able to shed some light on it. Version-Release number of selected component (if applicable): openldap-2.4.46-15.el8 How reproducible: Always Steps to Reproduce: 1. System running with our httpd package 2. Upgrade openldap-2.4.46 from release 11 to 15 Actual results: httpd syntax error on startup httpd: Syntax error on line 251 of httpd.conf: Cannot load modules/mod_security2.so into server: /lib64/libldap-2.4.so.2: undefined symbol: EVP_md2, version OPENSSL_1_1_0 Expected results: No syntax error on startup and a running system Additional info: Not sure if useful, but I've attached the output of pkgdiff between the mentioned releases.
