Detail
Problem Description: An updated rubygems package that fixes three security issues is now available for Red Hat Enterprise Linux 6. The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux Desktop Optional (v. 6) - noarch Red Hat Enterprise Linux HPC Node Optional (v. 6) - noarch Red Hat Enterprise Linux Server Optional (v. 6) - noarch Red Hat Enterprise Linux Workstation Optional (v. 6) - noarch 3. Description: RubyGems is the Ruby standard for publishing and managing third-party libraries. It was found that RubyGems did not verify SSL connections. This could lead to man-in-the-middle attacks. (CVE-2012-2126) It was found that, when using RubyGems, the connection could be redirected from HTTPS to HTTP. This could lead to a user believing they are installing a gem via HTTPS, when the connection may have been silently downgraded to HTTP. (CVE-2012-2125) It was discovered that the rubygems API validated version strings using an unsafe regular expression. An application making use of this API to process a version string from an untrusted source could be vulnerable to a denial of service attack through CPU exhaustion. (CVE-2013-4287) Red Hat would like to thank Rubygems upstream for reporting CVE-2013-4287. Upstream acknowledges Damir Sharipov as the original reporter. All rubygems users are advised to upgrade to this updated package, which contains backported patches to correct these issues. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/site/articles/11258 5. Bugs fixed (http://bugzilla.redhat.com/): 814718 - CVE-2012-2125 CVE-2012-2126 rubygems: Two security fixes in v1.8.23 1002364 - CVE-2013-4287 rubygems: version regex algorithmic complexity vulnerability |
