FINAL RESULTS:

data/r-cran-eipack-0.2-1/src/eiutil.c:132:5:  [4] (buffer) sprintf:
  Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
  vsnprintf.
    sprintf(tmp, "echo \"%.16f\" | gzip >>  %s", REAL(betaarray)[ii], CHAR(STRING_ELT(filenames,ii)));
data/r-cran-eipack-0.2-1/src/eiutil.c:133:9:  [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.
    ret=system(tmp);
data/r-cran-eipack-0.2-1/src/eiutil.c:131:5:  [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 tmp[500];
