Lately I get a bunch of these errors in my logs: [Wed May 19 22:26:37 2010] [error] [client 10.17.255.250] ALERT - canary mismatch on efree() - heap overflow detected (attacker '10.17.255.250', file '/var/www/oliophp/public_html/taggedEvents.php') [Wed May 19 22:26:37 2010] [error] [client 10.17.255.250] ALERT - canary mismatch on efree() - heap overflow detected (attacker '10.17.255.250', file '/var/www/oliophp/public_html/taggedEvents.php') [Wed May 19 22:26:37 2010] [error] [client 10.17.255.250] ALERT - canary mismatch on efree() - heap overflow detected (attacker '10.17.255.250', file '/var/www/oliophp/public_html/users.php') [Wed May 19 22:26:37 2010] [error] [client 10.17.255.250] ALERT - canary mismatch on efree() - heap overflow detected (attacker '10.17.255.250', file '/var/www/oliophp/public_html/events.php') [Wed May 19 22:26:37 2010] [error] [client 10.17.255.250] ALERT - canary mismatch on efree() - heap overflow detected (attacker '10.17.255.250', file '/var/www/oliophp/public_html/taggedEvents.php')
According to blogs it is a php related issue. Suhosin patch detects a memory overflow and complains. I was just wondering if the Olio php code is having any known mem. leaks. My php version on ubuntu: PHP 5.2.4-2ubuntu5 with Suhosin-Patch 0.9.6.2 (cli) (built: Feb 27 2008 20:46:51) Copyright (c) 1997-2007 The PHP Group Zend Engine v2.2.0, Copyright (c) 1998-2007 Zend Technologies It's too bad that I do not get a line on the php files that cause this. Has anyone come across this one before? ------------------------------------------------------------------- Kontorinis Vasileios Phd student, University of California San Diego San Diego, CA 92122 Cell. phone: (858) 717 6899 [email protected], [email protected] -------------------------------------------------------------------
