(CVE-2013-0156)Red Hat is aware that a public exploit for the CVE-2013-0156 issues isavailable that allows remote code execution in applications using Ruby onRails.Multiple input validation vulnerabilities were discovered inrubygem-activerecord. A remote attacker could possibly use these flaws toperform an SQL injection attack against an application usingrubygem-activerecord. (CVE-2012-2661, CVE-2012-2695, CVE-2012-6496,CVE-2013-0155)Multiple input validation vulnerabilities were discovered inrubygem-actionpack. A remote attacker could possibly use these flaws toperform an SQL injection attack against an application usingrubygem-actionpack and rubygem-activerecord. (CVE-2012-2660, CVE-2012-2694)Multiple cross-site scripting (XSS) flaws were found in rubygem-actionpack.A remote attacker could use these flaws to conduct XSS attacks againstusers of an application using rubygem-actionpack. (CVE-2012-3463,CVE-2012-3464, CVE-2012-3465)A flaw was found in the HTTP digest authentication implementation inrubygem-actionpack. A remote attacker could use this flaw to cause adenial of service of an application using rubygem-actionpack and digestauthentication. (CVE-2012-3424)Users are advised to upgrade to these updated rubygem-actionpack,rubygem-activesupport, and rubygem-activerecord packages, which resolvethese issues.
