CVE-2011-0755: Integer Overflow

First published: Wed Feb 02 2011(Updated: )

Integer overflow in the mt_rand function in PHP before 5.3.4 might make it easier for context-dependent attackers to predict the return values by leveraging a script's use of a large max parameter, as demonstrated by a value that exceeds mt_getrandmax.
