Yes, I have updated the Security page to include these newly announced
vulnerabilities. They are fixed in MariaDB-5.5.41 and MariaDB-10.0.16.

Generally it works as follows:
* Oracle discovers or learns about a security vulnerability in MySQL
* Oracle doesn't tell anyone and secretly fixes it
* Oracle releases a new - fixed - MySQL version
* We (MariaDB) pull in MySQL changes and release a new MariaDB version
  - this usually takes few days (up to a week)
* Oracle releases a CPU with very vague description of vulnerabilities
  - http://www.oracle.com/technetwork/topics/security/cpujan2015-1972971.html
* By that time a fixed MariaDB version is already released, I only need
  to add new CVE numbers to the Security page

So, generally, when new vulnerabilities are publically announced,
the latest MariaDB release already has them fixed. Even if Security
page doesn't tell so.
