FINAL RESULTS:

data/cclive-0.9.3/src/cc/exec.cpp:72:7:  [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[0], (char **)argv);
data/cclive-0.9.3/src/cc/fstream.h:66:12:  [4] (shell) system:
  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.
    boost::system::error_code ec; // Throw nothing.
data/cclive-0.9.3/src/cc/fstream.h:106:12:  [4] (shell) system:
  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.
    boost::system::error_code ec;
data/cclive-0.9.3/src/cc/options.h:392:21:  [3] (buffer) getenv:
  Environment variables are untrustable input if they can be set by an
  attacker. They can have any content and length, and the same variable can
  be set more than once (CWE-807, CWE-20). Check environment variables
  carefully before using them.
    const char *h = getenv("HOME");
data/cclive-0.9.3/src/cc/error.cpp:38:3:  [2] (buffer) char:
  Statically-sized arrays can be improperly restricted, leading to potential
  overflows or other issues (CWE-119!/CWE-120). Perform bounds checking, use
  functions that limit length, or ensure that the size is larger than the
  maximum possible length.
  char buf[256];
data/cclive-0.9.3/src/cc/error.h:42:3:  [2] (buffer) char:
  Statically-sized arrays can be improperly restricted, leading to potential
  overflows or other issues (CWE-119!/CWE-120). Perform bounds checking, use
  functions that limit length, or ensure that the size is larger than the
  maximum possible length.
  char buf[256];
data/cclive-0.9.3/src/cc/internal.h:63:13:  [2] (race) vfork:
  On some old systems, vfork() permits race conditions, and it's very
  difficult to use correctly (CWE-362). Use fork() instead.
    #define vfork fork
data/cclive-0.9.3/src/cc/log.h:128:8:  [2] (misc) open:
  Check when opening files - can an attacker redirect it (via symlinks),
  force the opening of special file type (e.g., device files), move things
  around to create a race condition, control its ancestors, or change its
  contents? (CWE-362).
    _s.open(_fpath.c_str(), _mode);
data/cclive-0.9.3/src/cc/background.cpp:69:3:  [1] (access) umask:
  Ensure that umask is given most restrictive possible setting (e.g., 066 or
  077) (CWE-732).
  umask(0);
data/cclive-0.9.3/src/cc/fstream.h:76:29:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
  static inline std::string read(const std::string& fpath)
data/cclive-0.9.3/src/cc/input.h:110:40:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
        extract_uris(dst, cc::fstream::read(r));
data/cclive-0.9.3/src/cc/input.h:126:38:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
      extract_uris(dst, cc::fstream::read(s));
data/cclive-0.9.3/src/cc/log.h:96:26:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
  inline std::streamsize read(char_type *t, std::streamsize n)
data/cclive-0.9.3/src/cc/log.h:98:8:  [1] (buffer) read:
  Check buffer boundaries if used in a loop including recursive loops
  (CWE-120, CWE-20).
    _s.read(t, n);
data/cclive-0.9.3/src/cc/options.h:393:14:  [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).
    if (h && strlen(h) >0)
data/cclive-0.9.3/src/compat/media_pt4.cpp:34:7:  [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).
  if (strlen(s) >0)
data/cclive-0.9.3/src/compat/media_pt9.cpp:34:20:  [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).
  if (s != NULL && strlen(s) >0)
data/cclive-0.9.3/src/compat/media_pt9.cpp:47:20:  [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).
  if (s != NULL && strlen(s) >0)
data/cclive-0.9.3/src/compat/query_pt9.cpp:77:11:  [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).
      if (strlen(id) >0)
