Note that Ubuntu, like many linux distributions, backports security fixes rather than upgrading to new versions of software to attempt to prevent the introduction of regressions and changes in behavior in released versions of software.

CVE-2010-3069 was addressed in http://www.ubuntu.com/usn/usn-987-1
CVE-2011-2522 and CVE-2011-2694 were addressed in http://www.ubuntu.com/usn/usn-1182-1
CVE-2011-0719 was addressed in http://www.ubuntu.com/usn/usn-1075-1
CVE-2010-1635 and CVE-2010-1642 can only kill the current connection of the attacker, the vulnerabilities do not affect the service as a whole, and as such have negligable security impact. They've also been addressed in maverick and subsequent releases.
