Detail
| 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. |
