-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Moderate: Red Hat Enterprise MRG Grid 2.4 security update Advisory ID: RHSA-2013:1851-01 Product: Red Hat Enterprise MRG for RHEL-5 Advisory URL: https://rhn.redhat.com/errata/RHSA-2013-1851.html Issue date: 2013-12-17 CVE Names: CVE-2012-2125 CVE-2012-2126 CVE-2013-4287 CVE-2013-4404 CVE-2013-4405 CVE-2013-4414 CVE-2013-4461 ===================================================================== 1. Summary: Updated Grid component packages that fix multiple security issues are now available for Red Hat Enterprise MRG 2.4 for Red Hat Enterprise Linux 5. 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: MRG Grid for RHEL 5 Server v.2 - noarch MRG Management for RHEL 5 Server v.2 - noarch 3. Description: Red Hat Enterprise MRG (Messaging, Realtime, and Grid) is a next-generation IT infrastructure for enterprise computing. MRG offers increased performance, reliability, interoperability, and faster computing for enterprise customers. MRG Grid provides high-throughput computing and enables enterprises to achieve higher peak computing capacity as well as improved infrastructure utilization by leveraging their existing technology to build high performance grids. MRG Grid provides a job-queueing mechanism, scheduling policy, and a priority scheme, as well as resource monitoring and resource management. Users submit their jobs to MRG Grid, where they are placed into a queue. MRG Grid then chooses when and where to run the jobs based upon a policy, carefully monitors their progress, and ultimately informs the user upon completion. 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 found that RubyGems did not verify SSL connections. This could lead to man-in-the-middle attacks. (CVE-2012-2126) 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) A flaw was found in the way cumin enforced user roles, allowing an unprivileged cumin user to access a range of resources without having the appropriate role. A remote, authenticated attacker could use this flaw to access privileged information, and perform a variety of privileged operations. (CVE-2013-4404) It was found that multiple forms in the cumin web interface did not protect against Cross-Site Request Forgery (CSRF) attacks. If a remote attacker could trick a user, who is logged into the cumin web interface, into visiting a specially crafted URL, the attacker could perform actions in the context of the logged in user. (CVE-2013-4405) It was found that cumin did not properly escape input from the "Max allowance" field in the "Set limit" form of the cumin web interface. A remote attacker could use this flaw to perform cross-site scripting (XSS) attacks against victims by tricking them into visiting a specially crafted URL. (CVE-2013-4414) A flaw was found in the way cumin parsed POST request data. A remote attacker could potentially use this flaw to perform SQL injection attacks on cumin's database. (CVE-2013-4461) Red Hat would like to thank Rubygems upstream for reporting CVE-2013-4287. Upstream acknowledges Damir Sharipov as the original reporter of CVE-2013-4287. The CVE-2013-4404, CVE-2013-4405, CVE-2013-4414, and CVE-2013-4461 issues were discovered by Tomáš Nováčik of the Red Hat MRG Quality Engineering team. All users of the Grid capabilities of Red Hat Enterprise MRG are advised to upgrade to these updated packages, which correct these issues. 4.
