SQL, login cookie checking is not case-sensitive, reducing total entropy and allowing easier brute force
Similar to bug 906745, when we check the database for validity of a users login cookie, MySQL does not do the check in a case-sensitive manner which lowers the bar to brute forcing someone's login cookie. We do store the IP address which helps some but it would be better if we pulled the cookie value from the db and then did the comparison in Perl like we did for the fix for bug 906745. Feel free to remove the privacy bit if you feel this is not necessarily a security problem but more of an enhancement. dkl
