RHSA-2013:0544: Important: Subscription Asset Manager 1.2 update

First published: Thu Feb 21 2013(Updated: )

Red Hat Subscription Asset Manager acts as a proxy for handling<br>subscription information and software updates on client machines.<br>It was discovered that Katello did not properly check user permissions when<br>handling certain requests. An authenticated remote attacker could use this<br>flaw to download consumer certificates or change settings of other users'<br>systems if they knew the target system's UUID. (CVE-2012-5603)<br>It was found that the<br>"/usr/share/katello/script/katello-generate-passphrase" utility, which is<br>run during the installation and configuration process, set world-readable<br>permissions on the "/etc/katello/secure/passphrase" file. A local attacker<br>could use this flaw to obtain the passphrase for Katello, giving them<br>access to information they would otherwise not have access to.<br>(CVE-2012-5561)<br>Note: After installing this update, ensure the<br>"/etc/katello/secure/passphrase" file is owned by the root user and group<br>and mode 0750 permissions. Sites should also consider re-creating the<br>Katello passphrase as this issue exposed it to local users.<br>Three flaws were found in rubygem-rack. A remote attacker could use these<br>flaws to perform a denial of service attack against applications using<br>rubygem-rack. (CVE-2012-6109, CVE-2013-0183, CVE-2013-0184)<br>It was found that ruby_parser from rubygem-ruby_parser created a temporary<br>file in an insecure way. A local attacker could use this flaw to perform a<br>symbolic link attack, overwriting arbitrary files accessible to the<br>application using ruby_parser. (CVE-2013-0162)<br>The CVE-2012-5603 issue was discovered by Lukas Zapletal of Red Hat;<br>CVE-2012-5561 was discovered by Aaron Weitekamp of the Red Hat Cloud<br>Quality Engineering team; and CVE-2013-0162 was discovered by Michael<br>Scherer of the Red Hat Regional IT team.<br>These updated Subscription Asset Manager packages include a number of bug<br>fixes and enhancements.
