FINAL RESULTS:

data/r-cran-mapproj-1.2.7/src/mapproject.c:83:2:  [4] (buffer) sprintf:
  Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
  vsnprintf.
	sprintf(errbuf, "Ambiguous projection specified: %s or %s?", theproj->name, i->name);
data/r-cran-mapproj-1.2.7/src/mapproject.c:88:2:  [4] (buffer) sprintf:
  Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
  vsnprintf.
	sprintf(errbuf, "%s projection requires %d parameter%s", i->name, i->npar, i->npar>1?"s":"");
data/r-cran-mapproj-1.2.7/src/mapproject.c:104:5:  [4] (buffer) sprintf:
  Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
  vsnprintf.
    sprintf(errbuf, "Unknown projection: %s", *name);
data/r-cran-mapproj-1.2.7/src/mapproject.c:73:10:  [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.
  static char errbuf[200];
data/r-cran-mapproj-1.2.7/src/mapproject.c:81:32:  [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(strncmp(*name, i->name, strlen(*name)) == 0) {
