Remote hole, DoS in MySQL

Wee writes "I just saw two pretty nasty vulnerabilities in MySQL were announced today by a German company called e-matters. From the annoucenment: "We have discovered two flaws within the MySQL server that can be used by any MySQL user to crash the server. Furthermore one of the flaws can be used to bypass the MySQL password check or to execute arbitrary code with the privileges of the user running mysqld. We have also discovered an arbitrary size heap overflow within the mysql client library and another vulnerability that allows to write '\0' to any memory address. Both flaws could allow DOS attacks against or arbitrary code execution within anything linked against libmysqlclient." Version 3.23.54 fixes the issues in 3.x. I couldn't find a patched version for the 4.0 beta."

not as bad as it seems...

Unless I'm misunderstanding this, these are local exploits only. No one can use these bugs unless he has a valid mysql account on the server in question. These vulnerabilities cannot be used by an external attacker (a website user, for example) to h4x0r the box.

In other words, my servers are not vulnerable. No one else but me has accounts on my boxen. Only a production box (a shell box doing web hosting, for example) where you have untrusted users would be vulnerable.

I'll update my box just as soon as my distro has a patch available, sure, but this event is a non-issue for me (this time).
