MySQL server and client vulnerabilities
MySQL 3.23.54 has just been released as a bug fix release and to patch multiple security vulnerabilities.
Vulnerabilities have been found in both the server and the client library. This means that not only the MySQL server needs to be reinstalled, but also everything compiled with the MySQL client library. This probably includes PHP, Apache, Perl libraries, your MTA, and others.
