Bug description: data leakage because of nonexisting boundary checking in
statements for MySQL41
Description:
------------
When I run ext/mysqli/tests/bug38710.phpt with PHP 5.2.6 and MySQL 4.1.20,
the scripts fails in a manner not anticipated by the test script.
The $text consists of 8240 a's followed by a string of non-printable
characters (cat -v shows "[EMAIL PROTECTED]@[EMAIL PROTECTED]@[EMAIL
PROTECTED]@^M
[EMAIL PROTECTED]@[EMAIL PROTECTED]@[EMAIL PROTECTED]@[EMAIL PROTECTED]@[EMAIL
PROTECTED]@^@"), followed by
more a's with the non-printable characters repeated every 8000 a's or so.
The string $text is not equal to str_repeat('a', 8191) for
mysqli_get_server_version($db)=401020, so the ACTUAL output is:
int(100000)
Done
Thanks.
Jim
Reproduce code:
---------------
<?php
include "connect.inc";
$db = new mysqli($host, $user, $passwd, "test");
$qry=$db->stmt_init();
$qry->prepare("SELECT REPEAT('a',100000)");
$qry->execute();
$qry->bind_result($text);
$qry->fetch();
if ($text !== str_repeat('a', mysqli_get_server_version($db) > 50110?
100000:(mysqli_get_server_version($db)>=50000? 8193:8191))) {
var_dump(strlen($text));
}
echo "Done";
?>
Expected result:
----------------
It should pass since this is expected behavior for MySQL prior to version
5.1
Actual result:
--------------
It failed
