    Several vulnerabilities were discovered in Rack, a modular Ruby
    webserver interface. The Common Vulnerabilites and Exposures project
    identifies the following vulnerabilities:
    
    CVE-2011-5036
    
        Rack computes hash values for form parameters without restricting
        the ability to trigger hash collisions predictably, which allows
        remote attackers to cause a denial of service (CPU consumption)
        by sending many crafted parameters. 
    
    CVE-2013-0184
    
        Vulnerability in Rack::Auth::AbstractRequest allows remote
        attackers to cause a denial of service via unknown vectors.
    
    CVE-2013-0263
    
        Rack::Session::Cookie allows remote attackers to guess the
        session cookie, gain privileges, and execute arbitrary code via a
        timing attack involving am HMAC comparison function that does not
        run in constant time. 
    
    For the oldstable distribution (squeeze), these problems have been fixed in
    version 1.1.0-4+squeeze1.
    
    The stable, testing and unstable distributions do not contain the
    librack-ruby package. They have already been addressed in version
    1.4.1-2.1 of the ruby-rack package.
    
    We recommend that you upgrade your librack-ruby packages.
