Red Hat Subscription Asset Manager 1.2, which fixes several security issues, multiple bugs, and adds various enhancements, is now available.

The Red Hat Security Response Team has rated this update as having important 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 Subscription Asset Manager acts as a proxy for handling subscription information and software updates on client machines.

It was discovered that Katello did not properly check user permissions when handling certain requests. An authenticated remote attacker could use this flaw to download consumer certificates or change settings of other users' systems if they knew the target system's UUID.
(CVE-2012-5603)

A vulnerability in rubygem-ldap_fluff allowed a remote attacker to bypass authentication and log into Subscription Asset Manager when a Microsoft Active Directory server was used as the back-end authentication server. (CVE-2012-5604)

It was found that the '/usr/share/katello/script/katello-generate-passphrase' utility, which is run during the installation and configuration process, set world-readable permissions on the '/etc/katello/secure/passphrase' file. A local attacker could use this flaw to obtain the passphrase for Katello, giving them access to information they would otherwise not have access to. (CVE-2012-5561)

Note: After installing this update, ensure the '/etc/katello/secure/passphrase' file is owned by the root user and group and mode 0750 permissions. Sites should also consider re-creating the Katello passphrase as this issue exposed it to local users.

Three flaws were found in rubygem-rack. A remote attacker could use these flaws to perform a denial of service attack against applications using rubygem-rack. (CVE-2012-6109, CVE-2013-0183, CVE-2013-0184)

A flaw was found in the way rubygem-activerecord dynamic finders extracted options from method parameters. A remote attacker could possibly use this flaw to perform SQL injection attacks against applications using the Active Record dynamic finder methods.
(CVE-2012-6496)

It was found that ruby_parser from rubygem-ruby_parser created a temporary file in an insecure way. A local attacker could use this flaw to perform a symbolic link attack, overwriting arbitrary files accessible to the application using ruby_parser. (CVE-2013-0162)

The CVE-2012-5603 issue was discovered by Lukas Zapletal of Red Hat;
CVE-2012-5604 was discovered by Og Maciel of Red Hat; CVE-2012-5561 was discovered by Aaron Weitekamp of the Red Hat Cloud Quality Engineering team; and CVE-2013-0162 was discovered by Michael Scherer of the Red Hat Regional IT team.

These updated Subscription Asset Manager packages include a number of bug fixes and enhancements. Space precludes documenting all of these changes in this advisory. Refer to the Red Hat Subscription Asset Manager 1.2 Release Notes for information about these changes :

https://access.redhat.com/knowledge/docs/en-US/ Red_Hat_Subscription_Asset_Manager/1.2/html/Release_Notes/index.html

All users of Red Hat Subscription Asset Manager are advised to upgrade to these updated packages, which fix these issues and add various enhancements.

Several vulnerabilities were discovered in Rack, a modular Ruby webserver interface. The Common Vulnerabilites and Exposures project identifies the following vulnerabilities :

  - CVE-2011-5036     Rack computes hash values for form parameters without     restricting the ability to trigger hash collisions     predictably, which allows remote attackers to cause a     denial of service (CPU consumption) by sending many     crafted parameters.

  - CVE-2013-0183     A remote attacker could cause a denial of service     (memory consumption and out-of-memory error) via a long     string in a Multipart HTTP packet.

  - CVE-2013-0184     A vulnerability in Rack::Auth::AbstractRequest allows     remote attackers to cause a denial of service via     unknown vectors.

  - CVE-2013-0263     Rack::Session::Cookie allows remote attackers to guess     the session cookie, gain privileges, and execute     arbitrary code via a timing attack involving an HMAC     comparison function that does not run in constant time.
