1. Summary:

 

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.

 

2. Relevant releases/architectures:

 

Red Hat Enterprise Linux Clustering (v. 5 server) - i386, ia64, ppc, x86_64

 

3. Description:

 

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.
