FINAL RESULTS:

data/backdoor-factory-3.4.2+dfsg/osslsigncode/osslsigncode.c:868:27:  [4] (format) fprintf:
  If format strings can be influenced by an attacker, they can be exploited
  (CWE-134). Use a constant for the format specification.
#define DO_EXIT_1(x, y) { fprintf(stderr, x, y); goto err_cleanup; }
data/backdoor-factory-3.4.2+dfsg/osslsigncode/osslsigncode.c:869:30:  [4] (format) fprintf:
  If format strings can be influenced by an attacker, they can be exploited
  (CWE-134). Use a constant for the format specification.

data/backdoor-factory-3.4.2+dfsg/osslsigncode/osslsigncode.c:2382:9:  [4] (misc) getpass:
  This function is obsolete and not portable. It was in SUSv2 but removed by
  POSIX.2. What it does exactly varies considerably between systems,
  particularly in where its prompt is displayed and where it gets its data
  (e.g., /dev/tty, stdin, stderr, etc.). In addition, some implementations
  overflow buffers. (CWE-676, CWE-120, CWE-20). Make the specific calls to do
  exactly what you want. If you continue to use it, or write your own, be
  sure to zero the password as soon as possible to avoid leaving the
  cleartext password visible in the process' address space.
	return getpass(prompt);
