[Regression Potential] * The fact that /bin/busybox wget https:// succeeds without TLS verification might be relied upon. If this issue is fixed, ensure that `--no-check-certificate` is honored. [Other Info] * Proposed fix pass `-verify_return_error` to s_client, unless `--no-check- certificate` is specified To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/busybox/+bug/1879533/+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
