#15333 [Com]: strndup access violation

ID: 15333 Comment by: home@NOSPAMwebpanache.com Reported By: david@harksystems.com Status: Open Bug Type: IIS related Operating System: Windows 2000 Pro PHP Version: 4.2.1 New Comment: Hi, Just to contribute had PHP with ISAPI dll working fine until a few days ago. It seems that applying the lastest Microsoft security fixes created the problem. The latest applied fix was MS02-048....

And it is reproductible. This is with the ISAPI version of PHP 4.2.2 under Windows XP. I get the following error message in the XP Error Log, when trying to access a page from another PC. A copy of the test file that causes the problem is at http://jf.larvoire.free.fr/calendrier.php3. Pressing on the "Next month" button crashes the PHP DLL. Jean-Francois Larvoire vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv The HTTP server encountered an unhandled exception while processing the ISAPI Application ' php4ts!zend_strndup + 0x2B + 0x17C99F70 '.

Cookie and session usage. The error of which I was receiving after about 15 page views: "PHP has encountered an Access Violation at 011929AE" was solved by... 1. updating all DLLs by copying DLLs included with PHP into C:\winnt\system32 2. having php4isapi.dll in both my ISAPI Filters and Home Directory > Configuration (under the Site properties) 3. setting Application Protection to Low (IIS Process) 4. restarting the server After doing the above, I haven't seen the error since. ------------------------------------------------------------------------ [2002-08-14 13:41:02] tgannon@colliers-seeley.com Hello, I can't come up with a working test case but I have an idea which might help narrow the search. I have two PHP applications, one of which works fine in IIS and the other of which causes this bug frequently. The only significant difference that I can find between the two apps is that the one that hangs IIS uses sessions and cookies, whereas the stable one does not. I removed the calls to session_start and session_register from the unstable one, and after some testing it appears to still work. I'll give an update after some more testing has been done. Windows 2000 Server, Service pack 3 + .NET Framework (sp2) PHP 4.2.2 as ISAPI ------------------------------------------------------------------------ [2002-07-26 14:10:17] agustinchernitsky@hotmail.com James, Win2K 2.00.2195 SP2 IIS 5.0.2195.2966 PHP 4.2.1 Create a Web Site with ISAPI, make the PHP do some lookups in MySQL (Install PHPMyAdmin). That should do it... No security Service Packs are Installed, Just SP2. ------------------------------------------------------------------------ [2002-07-23 18:26:19] ken@rockies.ca Also getting this bug with PHP 4.2.2 ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
