FINAL RESULTS:

data/ssh-contact-0.7/src/client.c:298:11:  [2] (integer) atoi:
  Unless checked, the resulting number can exceed the expected range
  (CWE-190). If source untrusted, check both minimum and maximum, even if the
  input had no minus sign (large numbers can roll over into negative number;
  consider saving to an unsigned value if that is intended).
      i = atoi (str) - 1;
data/ssh-contact-0.7/src/client.c:297:11:  [1] (buffer) strlen:
  Does not handle strings that are not \0-terminated; if given one it may
  perform an over-read (it could cause a crash if unprotected) (CWE-126).
      str[strlen (str) - 1] = '\0';
