Examining data/retry-1.0.4/retry.c

FINAL RESULTS:

data/retry-1.0.4/retry.c:176:5:  [4] (format) printf:
  If format strings can be influenced by an attacker, they can be exploited
  (CWE-134). Use a constant for the format specification.
    printf(PACKAGE_STRING "\n");
data/retry-1.0.4/retry.c:490:13:  [4] (shell) execvp:
  This causes a new program to execute and is difficult to use safely
  (CWE-78). try using a library call that implements the same functionality
  if available.
            execvp(argv[optind], argv + optind);
data/retry-1.0.4/retry.c:395:17:  [3] (buffer) getopt_long:
  Some older implementations do not protect against internal buffer overflows
  (CWE-120, CWE-20). Check implementation on installation, or limit the size
  of all string inputs.
    while ((c = getopt_long(argc, argv, "d:m:t:u:w:hv", long_options, NULL)) != -1) {
data/retry-1.0.4/retry.c:195:19:  [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).
            len = strlen(criteria);
data/retry-1.0.4/retry.c:307:27:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
                    num = read(pumps[i].rfd, base + pumps[i].len, BUFFER_SIZE);
