Examining data/dhis-mx-sendmail-engine-5.0/dhis-mx-sendmail-engine.c

FINAL RESULTS:

data/dhis-mx-sendmail-engine-5.0/dhis-mx-sendmail-engine.c:48:10:  [4] (format) syslog:
  If syslog's format strings can be influenced by an attacker, they can be
  exploited (CWE-134). Use a constant format string for syslog.

  [MS-banned] (CWE-120). Consider using strcat_s, strncat, strlcat, or
  snprintf (warning: strncat is easily misused).
