FINAL RESULTS:

data/libfile-fcntllock-perl-0.22/Pure_build/builder.c:69:5:  [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 packstr[ 128 ] = "";
data/libfile-fcntllock-perl-0.22/Pure_build/builder.c:106:4:  [2] (buffer) sprintf:
  Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
  vsnprintf. Risk is low because the source has a constant maximum length.
			sprintf( packstr + strlen( packstr ), "x%lu",
data/libfile-fcntllock-perl-0.22/Pure_build/builder.c:145:9:  [2] (buffer) sprintf:
  Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
  vsnprintf. Risk is low because the source has a constant maximum length.
        sprintf( packstr + strlen( packstr ), "x%lu",
data/libfile-fcntllock-perl-0.22/Pure_build/builder.c:106:23:  [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).
			sprintf( packstr + strlen( packstr ), "x%lu",
data/libfile-fcntllock-perl-0.22/Pure_build/builder.c:113:5:  [1] (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). Risk is low because the
  source is a constant character.
				strcat( packstr, "c" );
data/libfile-fcntllock-perl-0.22/Pure_build/builder.c:117:5:  [1] (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). Risk is low because the
  source is a constant character.
				strcat( packstr, "s" );
data/libfile-fcntllock-perl-0.22/Pure_build/builder.c:121:5:  [1] (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). Risk is low because the
  source is a constant character.
				strcat( packstr, "l" );
data/libfile-fcntllock-perl-0.22/Pure_build/builder.c:134:5:  [1] (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). Risk is low because the
  source is a constant character.
				strcat( packstr, "q" );
data/libfile-fcntllock-perl-0.22/Pure_build/builder.c:145:28:  [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).
        sprintf( packstr + strlen( packstr ), "x%lu",
