             Summary: dundi_read_result crash
                 Key: ASTERISK-21205
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-21205
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: PBX/pbx_dundi
    Affects Versions: 11.2.1
         Environment: gentoo linux
kernel 3.7.3
            Reporter: Jaco Kroon
            Severity: Critical


Should dundi_lookup_internal return a negative number then so will dundi_lookup, which usually gets assigned to num_results, which is an unsigned int.  Later when sorting this number is taken "as is", which then results in an out-of-bounds situation and a segfault (usually).
