Just one, which I think means that either the attacker tried not to look suspicious, or just that it was some random bug that triggered the first time.

No, PAX killed it with SIGKILL so I couldn't debug it at all.

I'm anyway pretty sure that this wasn't caused at least directly by my code. There's very few buffers in stack, and they're all written to with bounds checking so even corrupted heap shouldn't cause this. Received on Wed Apr 9 11:12:39 2003
