Welcome to the Security Alerts column, an overview of new Unix and open source security-related advisories and news. Problems this week include buffer overflows in splitvt, bing, write, and Lotus Domino's SMTP server; temporary file problems with webmin and Apache's mod_rewrite; format string problems with icecast; ip firewalling problems with FreeBSD; and SQL problems in Postaci.

    An interesting exercise is to trade places with the attacker. Put yourself in their shoes and see what unexpected things you can make your system or software do when you put your mind into it. You may be surprised with what you find out, and that is much better than being surprised by a system cracker.
