| Summary | 0001100: bconsole crashes when a pam authentication aborts | ||||
| Description | I want to authenticate using bconsole on a director with PAM enabled. The bconsole tries to authenticate using the interactive mode but stops working with the following output: "free(): double free detected in tcache 2 BAREOS interrupted by signal 6: IOT trap bconsole, bconsole got signal 6 - IOT trap. Attempting traceback." In the director's logfile I can find this: bareos-dir (200): dird/auth_pam.cc:193-0 PAM authentication failed: Error in service module bareos-dir (10): dird/authenticate_console.cc:355-0 ERROR: Unable to authenticate console "PamConsole" at client: | ||||
| Steps To Reproduce | I used this code from the bconsole-pam test in the Bareos systemtests (shown only snippets): # etc/pam.d/bareos.in has to be adapted to the right system paths and renamed to etc/pam.d/bareos export PAM_WRAPPER=1 export PAM_WRAPPER_SERVICE_DIR=etc/pam.d/bareos /usr/lib64/libpam_wrapper.so ../../../core/src/dird/bareos-dir -f -c etc/bareos/ -d200 ../../../core/src/console/bconsole -c etc/bareos/ bconsole then asks for a password. After pressing enter the console crashes. | ||||
| Additional Information | The bug severity of minor is only justifiable because up to now this bug is known to appear in this special test-environment. | ||||
