#15106 [Ctl->Csd]: import_request_variables segfault...

ID: 15106 Updated by: zeev@php.net Reported By: robert@artnickel.com -Status: Critical +Status: Closed Bug Type: Reproducible crash Operating System: Linux 2.4.10 PHP Version: 4.3.0-dev New Comment: Fixed for 4.2.3 Previous Comments: ------------------------------------------------------------------------ [2002-06-17 19:42:05] sniper@php.net Reproduced with latest CVS HEAD. Making this 'fix before 4.3.0 is released' critical. ------------------------------------------------------------------------ [2002-01-18 14:32:01] robert@artnickel.com Usage of the import_request_variables function more than once with the same value for the method type and prefix string will produce a segfault. The example: <html> <body> <? @import_request_variables("g", ""); foreach($_GET as $b=>$c) print "Key: $b | Value: $c<br>\n"; flush(); @import_request_variables("g", ""); foreach($_GET as $b=>$c) print "Key: $b | Value: $c<br>\n"; ?> </body> </html> The second foreach loop will never be reached and the flush() call will be ineffectual since the module segfaults and doesn't care about the buffer. The segfault only affects the php module and will NOT bring down the apache server. Although not shown here for space conservation, if by chance this is done via an include, the results are mixed. I have some that will cause a segfault ans some that don't and I haven't figured out the difference between them. Specifics: Apache 1.3.22 Linux 2.4.10 kernel PHP running as a DSO with apache using the php.ini-recommended with very few modifications (available on request if necessary) Thanks, --Robert ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=15106&edit=1
