Sebastian,

this part of the patch: /**

• • protect against deep recursion attack CVE-2006-1549,
• • 1000 seems to be more than enough
• • @see http://www.php-security.org/MOPB/MOPB-02-2007.html
• • @see http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-1549
• */

+if (count($GLOBALS) > 1000) {

• die('possible deep recurse attack');

+}

is not reached when I test the attack of MOPB-02, it's the other part that protects for this attack.

Do you know in which case this code would trigger? In the case of an attempt to override $GLOBALS?

it should trigger if and only if register_globals is on

I cannot make this code trigger when register_globals is on, it's always the protection in PMA_arrayWalkRecursive() that triggers.

I'm attacking with curl http://127.0.0.1/phpmyadmin/ -d a`php -r 'echo str_repeat("[a]",20000);'`=1

do you have some other attack in mind?
