#43861 [Opn]: suhosin patch detects heap overflow on mssql_free_result()

ID: 43861 Updated by: rasmus@php.net Reported By: skennedy at vcn dot com Status: Open Bug Type: MSSQL related Operating System: FreeBSD 6.2 PHP Version: 5.2.5 New Comment: Again, that valgrind output does not show an overflow. Either the problem is being masked by the suhosin patch, or it is a false positive. Trying removing the suhosin patch and do the valgrind check again. Previous Comments: ------------------------------------------------------------------------ [2008-01-30 17:21:28] skennedy at vcn dot com Rasmus, I tested if this same heap overflow would occur on my Linux box (Debian 4.0) by compiling my own very basic PHP 5.2.5 (./configure --with-mssql) w/ Sushosin patch. The result: same exact error as on FreeBSD. The original valgrind output I submitted was from the PHP installed via a Debian package. So I recompiled my PHP again this time without Sushosin patch and ran valgrind again. Updated output: http://www.bandwidthbuilders.com/valgrind-output.txt Let me know if you need me to do anything else. Thanks. ------------------------------------------------------------------------ [2008-01-30 01:09:03] rasmus@php.net I know that Valgrind output looks scary, but that is actually a clean run. The dlopen/dlclose stuff is normal. Are you seeing the same warning on this setup? ------------------------------------------------------------------------ [2008-01-30 00:09:25] skennedy at vcn dot com http://www.bandwidthbuilders.com/valgrind-output.txt ------------------------------------------------------------------------ [2008-01-28 23:35:12] tony2001@php.net Would be nice if you try it on some Linux machine. ------------------------------------------------------------------------ [2008-01-28 21:51:54] skennedy at vcn dot com Apparently amd64/FreeBSD cannot run valgrind. I get this when trying to install it: ===> valgrind-352_7 is only for i386, while you are running amd64.*** Error code 1 Is there anything else that's amd64/FreeBSD friendly I can use? ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
