[Test plan] Run the command of the package being tested in gdb -ex "break CONF_modules_load_file" -ex "run" --args and make sure it only breaks one. [Where problems could occur] wget: This is an upstream change that changes initialization and is in use in later releases. Since it mostly removes an unneeded call to the load file function, a regression could be a config file being ignored, but it seems unlikely given the use in later releases [Original bug report] "double free" error is seen when using curl utility. Error is from libcrypto.so which is part of the OpenSSL package. This happens only when OpenSSL is configured to use a dynamic engine. OpenSSL version is 1.1.1f The issue is not encountered if http://www.openssl.org/source/openssl-1.1.1f.tar.gz is used instead. OpenSSL can be configured to use a dynamic engine by editing the default openssl config file which is located at '/etc/ssl/openssl.cnf' on Ubuntu systems. On Bluefield systems, config diff to enable PKA dynamic engine, is as below: +openssl_conf = conf_section + # Extra OBJECT IDENTIFIER info: #oid_file = $ENV::HOME/.oid oid_section = new_oids +[ conf_section ] +engines = engine_section + +[ engine_section ] +bf = bf_section + +[ bf_section ] +engine_id=pka +dynamic_path=/usr/lib/aarch64-linux-gnu/engines-1.1/pka.so +init=0 + engine_id above refers to dynamic engine name/identifier. dynamic_path points to the .so file for the dynamic engine. # curl -O https://tpo.pe/pathogen.vim double free or corruption (out) Aborted (core dumped) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openssl/+bug/1921518/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
