FINAL RESULTS:

data/r-cran-progress-1.2.2/inst/include/RProgress.h:290:20:  [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.
    char *v = std::getenv("RSTUDIO");

    char *v = std::getenv("R_GUI_APP_VERSION");
data/r-cran-progress-1.2.2/inst/include/RProgress.h:259:11:  [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.
    const char symbols[4] = {'-', '\\', '|', '/'};
data/r-cran-progress-1.2.2/tests/testthat/progresstest/src/test.cpp:16:5:  [1] (obsolete) usleep:
  This C routine is considered obsolete (as opposed to the shell command by
  the same name). The interaction of this function with SIGALRM and other
  timer functions such as sleep(), alarm(), setitimer(), and nanosleep() is
  unspecified (CWE-676). Use nanosleep(2) or setitimer(2) instead.
    usleep( (useconds_t) (2.0 / 100 * 1000000));
