http://blog.torproject.org/blog/tor-02129-released-security-patches
https://gitweb.torproject.org/tor.git/blob/refs/heads/release-0.2.2:/ChangeLog
The specifics of the CVEs are as follows:
* Name: CVE-2011-0015
* Reference: https://trac.torproject.org/projects/tor/ticket/2324
Tor before 0.2.1.29 and 0.2.2.x before 0.2.2.21-alpha does not
properly check the amount of compression in zlib-compressed data,
which allows remote attackers to cause a denial of service via a large
compression factor.
* Name: CVE-2011-0016
* Reference: https://trac.torproject.org/projects/tor/ticket/2384
