Ok I was able to reproduce the problem on a new VM Steps:
1) Create fresh vm: done, installed Ubuntu 8.04.2 amd64 as denoted by # lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 8.04.3 LTS (it shows .3 because I issued the command after the update I think) Release: 8.04 Codename: hardy 2) Update system and reboot: done 3) Install LAMP Server packages: done. I didn't install mysql, only apache2 and php5 (I have the db on another machine) 4) We need ODBC: done. Installed php5-odbc libmyodbc unixodbc, copied the sample configurations and adapted odbc.ini to connect to my db server. Plus I tested the connection with isql and worked. 5) Create a PHP test page: done. I've attached the info.html file (with ip and domain hidden for privacy reasons) 6) I already have a database ready (MySQL 5.0.24) 7) Create PHP page to test odbc: done. It's the exact copy of your example script, with the connection data and the table changed of course 8) Try the script.. and here the browser serves me the file as a download. In /var/log/apache2/error.log there is the canary error. Here's the complete log: [Mon Jul 20 11:39:37 2009] [notice] Apache/2.2.8 (Ubuntu) PHP/5.2.4-2ubuntu5.6 with Suhosin-Patch configured -- resuming normal operations [Mon Jul 20 11:47:47 2009] [error] [client <client ip>] ALERT - canary mismatch on efree() - heap overflow detected (attacker '<client ip>', file '/var/www/odbctest.php', line 11), referer: http://<server ip>/ [Mon Jul 20 11:47:47 2009] [error] [client <client ip>] ALERT - canary mismatch on efree() - heap overflow detected (attacker '<client ip>', file '/var/www/odbctest.php', line 11), referer: http://<server ip>/ 9) and 10) no sense doing these.
