             Summary: default_from_user can crash with certain configuration backends
                 Key: ASTERISK-25390
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-25390
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
            Reporter: Mark Michelson


The recently-added default_from_user option was implemented in such a way that certain backend configuration storage methods (e.g. a database) resulted in a crash. This was because the global configuration structure is short-lived enough to result in referencing freed memory.

The retrieved default_from_user needs to be copied out of the global configuration structure so that a crash does not occur.
