Package        : librack-ruby
Vulnerability  : several
Problem type   : remote
Debian-specific: no
CVE ID         : CVE-2011-5036 CVE-2013-0183 CVE-2013-0184 CVE-2013-0263
Debian Bug     : 653963 698440 700226

The update of librack-ruby in DSA-2783-1 also addressed CVE-2013-0183.
The patch applied breaks rails applications like redmine (see Debian Bug
#727187). Updated packages are available to address this problem.

For reference, the original advisory text follows:

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.
