FINAL RESULTS:

data/mysqltcl-3.052/generic/mysqltcl.c:201:2:  [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(objPtr->bytes,state->MysqlNullvalue);
data/mysqltcl-3.052/generic/mysqltcl.c:228:9:  [4] (buffer) sprintf:
  Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
  vsnprintf.
    len=sprintf(buffer, "%s%d", (handle->type==HT_QUERY) ? "query" : MysqlHandlePrefix,handle->number);    
data/mysqltcl-3.052/generic/mysqltcl.c:230:5:  [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(objPtr->bytes, buffer);

  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).

data/mysqltcl-3.052/generic/mysqltcl.c:2025:4:  [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).

data/mysqltcl-3.052/generic/mysqltcl.c:58:3:  [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 database[MYSQL_NAME_LEN];  /* Db name, if selected; NULL otherwise. */
data/mysqltcl-3.052/generic/mysqltcl.c:221:5:  [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 buffer[MYSQL_HPREFIX_LEN+TCL_DOUBLE_SPACE+1];
data/mysqltcl-3.052/generic/mysqltcl.c:481:3:  [2] (buffer) memcpy:
  Does not check for buffer overflows when copying to destination (CWE-120).
  Make sure destination can always hold the source data.
  memcpy(qhandle,handle,sizeof(MysqlTclHandle));
data/mysqltcl-3.052/generic/mysqltcl.c:2478:12:  [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/mysqltcl-3.052/generic/mysqltcl.c:2648:3:  [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 nbuf[MYSQL_SMALL_SIZE];
data/mysqltcl-3.052/generic/mysqltcl.c:199:13:  [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).
	valueLen = strlen(state->MysqlNullvalue);
data/mysqltcl-3.052/generic/mysqltcl.c:933:5:  [1] (buffer) strncpy:
  Easily used incorrectly; doesn't always \0-terminate or check for invalid
  pointers [MS-banned] (CWE-120).
    strncpy(handle->database, db, MYSQL_NAME_LEN) ;
data/mysqltcl-3.052/generic/mysqltcl.c:2755:8:  [1] (buffer) strlen:
