FINAL RESULTS:

data/libnfsidmap-regex-1.2/regex.c:370:2:  [4] (buffer) strcpy:
  Does not check for buffer overflows when copying to destination [MS-banned]
  (CWE-120). Consider using snprintf, strcpy_s, or strlcpy (warning: strncpy
  easily misused).
	strcpy(dest, prefix);
data/libnfsidmap-regex-1.2/regex.c:371:2:  [4] (buffer) strcat:
  Does not check for buffer overflows when concatenating to destination
  [MS-banned] (CWE-120). Consider using strcat_s, strncat, strlcat, or
  snprintf (warning: strncat is easily misused).
	strcat(dest, name_prefix);
data/libnfsidmap-regex-1.2/regex.c:372:2:  [4] (buffer) strcat:
  Does not check for buffer overflows when concatenating to destination
  [MS-banned] (CWE-120). Consider using strcat_s, strncat, strlcat, or
  snprintf (warning: strncat is easily misused).
	strcat(dest, localname);
data/libnfsidmap-regex-1.2/regex.c:373:2:  [4] (buffer) strcat:
  Does not check for buffer overflows when concatenating to destination

  snprintf (warning: strncat is easily misused).

data/libnfsidmap-regex-1.2/regex.c:86:9:  [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.

data/libnfsidmap-regex-1.2/regex.c:367:6:  [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).
