Edit report at https://bugs.php.net/bug.php?id=62397&edit=1 ID: 62397 User updated by: spamik at yum dot pl Reported by: spamik at yum dot pl Summary: disable_functions = eval does not work Status: Not a bug -Type: Bug +Type: Feature/Change Request Package: *General Issues PHP Version: 5.3.14 Block user comment: N Private report: N New Comment: I think that that not only should be done but also made default php behavior, to stop widespread madness of php code infection. Eval should be by default disabled in php like 5.5 ... Previous Comments: ------------------------------------------------------------------------ [2012-06-24 04:02:31] spamik at yum dot pl feature request then ------------------------------------------------------------------------ [2012-06-24 03:59:29] krzf83 at gmail dot com treat it as feature request if it helps you sleep at night. However this issue is critical in face of current mailicous code boom. Eval (by base64_encode etc) does not allow for any scanning and detection. This funcionality of php had begun its downfall really. People are migrating to other languages just because infections there are rare and code cannot be just like that obfucated! ------------------------------------------------------------------------ [2012-06-24 03:56:32] krzf83 at gmail dot com "eval is not a function but language construct" - that might be the reason why disable_functions don't work on it now but that does not mean it could not or should not. I would not dismiss this isssue so easily. Eval problem caused that php is currently (almost) only one language is so often infected. It allows for attacker to hide code, purpose, use ecodings (like base64) to diminish any hope of detection by searching for common traits (like antivirus software does). Eval is a functionality of php and could be disabled if apropriate modifications to php source code were made. ------------------------------------------------------------------------ [2012-06-23 12:52:55] bobwei9 at hotmail dot com Why can't you simply add a new core directive for disabling this language construct? ------------------------------------------------------------------------ [2012-06-23 12:29:45] laruence@php.net as I said, eval is not a *function*, so disable_*functions* has no effect to eval.. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
