Updated Grid component packages that fix multiple security issues are now available for Red Hat Enterprise MRG 2.4 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.

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 Tomas Novacik 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.

The remote Solaris system is missing necessary patches to address security updates :

  - Heap-based buffer overflow in Ruby 1.8, 1.9 before     1.9.3-p484, 2.0 before 2.0.0-p353, 2.1 before 2.1.0     preview2, and trunk before revision 43780 allows     context-dependent attackers to cause a denial of service     (segmentation fault) and possibly execute arbitrary code     via a string that is converted to a floating point     value, as demonstrated using (1) the to_f method or (2)     JSON.parse. (CVE-2013-4164)

  - Algorithmic complexity vulnerability in     Gem::Version::VERSION_PATTERN in lib/     rubygems/version.rb in RubyGems before 1.8.23.1, 1.8.24     through 1.8.25, 2.0.x before 2.0.8, and 2.1.x before     2.1.0, as used in Ruby 1.9.0 through 2.0.0p247, allows     remote attackers to cause a denial of service (CPU     consumption) via a crafted gem version that triggers a     large amount of backtracking in a regular expression.
    (CVE-2013-4287)

  - Algorithmic complexity vulnerability in     Gem::Version::ANCHORED_VERSION_PATTERN in     lib/rubygems/version.rb in RubyGems before 1.8.23.2,     1.8.24 through 1.8.26, 2.0.x before 2.0.10, and 2.1.x     before 2.1.5, as used in Ruby 1.9.0 through 2.0.0p247,     allows remote attackers to cause a denial of service     (CPU consumption) via a crafted gem version that     triggers a large amount of backtracking in a regular     expression. NOTE: this issue is due to an incomplete fix     for CVE-2013-4287. (CVE-2013-4363)

According to its self-reported version number, the Puppet Enterprise install on the remote host is a version prior to 3.1.0.  As a result, it is reportedly affected by multiple vulnerabilities :

  - An error exists related to the Fiddle and DL modules,     '$SAFE' level verification and object handling that     could allow an attacker to modify system calls.
    (CVE-2013-2065)

  - A remote code execution vulnerability exists that is     triggered when handling a YAML report. This could allow     a remote attacker to execute arbitrary code.
    (CVE-2013-4957)

  - A console account brute-force vulnerability exists that     could allow an attacker to brute-force a known user's     password. (CVE-2013-4965)

  - A RubyGems algorithmic complexity denial of service     vulnerability exists that could allow an attacker to     cause a denial of service through CPU consumption.
