    It has been discovered by "frosty_un" that a design flaw in Tor, an online
    privacy tool, allows malicious relay servers to learn certain information
    that they should not be able to learn. Specifically, a relay that a user
    connects to directly could learn which other relays that user is 
    connected to directly. In combination with other attacks, this issue 
    can lead to deanonymizing the user.  The Common Vulnerabilities and 
    Exposures project has assigned CVE-2011-2768 to this issue.
    
    In addition to fixing the above mentioned issues, the updates to oldstable
    and stable fix a number of less critical issues (CVE-2011-2769). Please 
    see this posting from the Tor blog for more information:
    https://blog.torproject.org/blog/tor-02234-released-security-patches
    
    For the oldstable distribution (lenny), this problem has been fixed in
    version 0.2.1.31-1~lenny+1. Due to technical limitations in the Debian
    archive scripts, the update cannot be released synchronously with the
    packages for stable. It will be released shortly.
    
    For the stable distribution (squeeze), this problem has been fixed in
    version 0.2.1.31-1.
    
    For the unstable and testing distributions, this problem has been fixed in
    version 0.2.2.34-1.
    
    For the experimental distribution, this problem have has fixed in version
    0.2.3.6-alpha-1.
    
    We recommend that you upgrade your tor packages.
