FINAL RESULTS:

data/dpaste-0.4.0/src/log.cpp:35:15:  [4] (format) vsnprintf:
  If format strings can be influenced by an attacker, they can be exploited,
  and note that sprintf variations do not always \0-terminate (CWE-134). Use
  a constant for the format specification.
    int ret = vsnprintf(buffer.data(), buffer.size(), m, args);
data/dpaste-0.4.0/src/main.cpp:67:19:  [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 ((opt = getopt_long(argc, argv, "hvg:r:s", long_options, nullptr)) != -1) {
data/dpaste-0.4.0/src/bin.cpp:115:18:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
    input_stream.read(reinterpret_cast<char*>(buffer.data()), dht::MAX_VALUE_SIZE);
data/dpaste-0.4.0/src/gpgcrypto.cpp:43:23:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
    while ((bytes = d.read(buf.data(), BUFLEN)) > 0)
