Besides fixing Debian Bug #744018, the release fixes the following two vulnerabilities (as mentioned in the bug report):
- CVE-2014-0165 WordPress privilege escalation: prevent contributors from publishing posts
- CVE-2014-0166 WordPress potential authentication cookie forgery
I recommend if you use the Debian package to upgrade as soon as it is available.
