ID: 51436 Comment by: crrodriguez at opensuse dot org Reported by: andreas at andreas dot org Summary: LCG entropy fix insufficient, uniqid leaks entropy, leads to weak session IDs Status: Assigned Type: Bug Package: *Encryption and hash functions Operating System: all PHP Version: 5.3.2 Assigned To: pajoye New Comment: I think trying RAND_pseudo_bytes() if -lcrypto is found in the system first and then your_own_function ight be a suitable approach. Previous Comments: ------------------------------------------------------------------------ [2010-04-09 18:18:32] paj...@php.net That's the idea but not using zend's mm which is incomplete. ------------------------------------------------------------------------ [2010-04-09 17:51:14] crrodriguez at opensuse dot org I think uniqid() should also use zend_mm_random()-like random value when more_entropy is set to true instead of the LCG ... ------------------------------------------------------------------------ [2010-04-07 17:44:16] paj...@php.net And assigned to me, almost done with the patch we discussed. ------------------------------------------------------------------------ [2010-04-07 17:43:49] paj...@php.net Well, the easiest to "backport" something now and here is to use the given settings. You can do it right now. ------------------------------------------------------------------------ [2010-04-07 17:21:47] andreas at andreas dot org I strongly suggest backporting. Also, the fact that uniqid() values are predictable too needs addressing. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
