The remote Red Hat host is missing one or more security updates.
Updated Grid component packages that fix multiple security issues are
now available for Red Hat Enterprise MRG 2.4 for Red Hat Enterprise
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.
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
