Updated conga packages that fix multiple security issues and several bugs are now available for Red Hat Enterprise Linux 5.

Red Hat Product Security 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.

The Conga project is a management system for remote workstations. It consists of luci, which is a secure web-based front end, and ricci, which is a secure daemon that dispatches incoming messages to underlying management modules.

It was discovered that Plone, included as a part of luci, did not properly protect the administrator interface (control panel). A remote attacker could use this flaw to inject a specially crafted Python statement or script into Plone's restricted Python sandbox that, when the administrator interface was accessed, would be executed with the privileges of that administrator user. (CVE-2012-5485)

It was discovered that Plone, included as a part of luci, did not properly sanitize HTTP headers provided within certain URL requests. A remote attacker could use a specially crafted URL that, when processed, would cause the injected HTTP headers to be returned as a part of the Plone HTTP response, potentially allowing the attacker to perform other more advanced attacks. (CVE-2012-5486)

Multiple information leak flaws were found in the way conga processed luci site extension-related URL requests. A remote, unauthenticated attacker could issue a specially crafted HTTP request that, when processed, would result in unauthorized information disclosure.
(CVE-2013-6496)

It was discovered that various components in the luci site extension-related URLs were not properly restricted to administrative users. A remote, authenticated attacker could escalate their privileges to perform certain actions that should be restricted to administrative users, such as adding users and systems, and viewing log data. (CVE-2014-3521)

It was discovered that Plone, included as a part of luci, did not properly protect the privilege of running RestrictedPython scripts. A remote attacker could use a specially crafted URL that, when processed, would allow the attacker to submit and perform expensive computations or, in conjunction with other attacks, be able to access or alter privileged information. (CVE-2012-5488)

It was discovered that Plone, included as a part of luci, did not properly enforce permissions checks on the membership database. A remote attacker could use a specially crafted URL that, when processed, could allow the attacker to enumerate user account names.
(CVE-2012-5497)

It was discovered that Plone, included as a part of luci, did not properly handle the processing of requests for certain collections. A remote attacker could use a specially crafted URL that, when processed, would lead to excessive I/O and/or cache resource consumption. (CVE-2012-5498)

It was discovered that Plone, included as a part of luci, did not properly handle the processing of very large values passed to an internal utility function. A remote attacker could use a specially crafted URL that, when processed, would lead to excessive memory consumption. (CVE-2012-5499)

It was discovered that Plone, included as a part of luci, allowed a remote anonymous user to change titles of content items due to improper permissions checks. (CVE-2012-5500)

The CVE-2014-3521 issue was discovered by Radek Steiger of Red Hat, and the CVE-2013-6496 issue was discovered by Jan Pokorny of Red Hat.

In addition, these updated conga packages include several bug fixes.
Space precludes documenting all of these changes in this advisory.
Users are directed to the Red Hat Enterprise Linux 5.11 Technical Notes, linked to in the References section, for information on the most significant of these changes

All conga users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. After installing this update, the luci and ricci services will be restarted automatically.
