FINAL RESULTS:

data/r-cran-colorspace-2.0-0+dfsg/src/colorspace.c:1312:5:  [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 hex[8];
data/r-cran-colorspace-2.0-0+dfsg/src/colorspace.c:570:13:  [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(CHAR(STRING_ELT(hex, i))) != 7 ||
