Summary: Updated spacewalk-backend packages that fix one security issue are now available for Red Hat Network Satellite 5.4 on Red Hat Enterprise Linux 6. The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. 2. Relevant releases/architectures: Red Hat Network Satellite Server 5.4 (RHEL v.6) - noarch 3. Description: Red Hat Network (RHN) Satellite is a systems management tool for Linux-based infrastructures. It allows for provisioning, monitoring, and remote management of multiple Linux deployments with a single, centralized tool. It was found that a remote attacker could upload packages to an RHN Satellite server's NULL organization without any authorization or authentication. (The NULL organization stores packages synced from RHN Hosted.) Although an attacker cannot put packages into an arbitrary channel and have client systems download them, they could use the flaw to consume all the free space in the partition (/var/) used to store synced packages. With no free space, Satellite would be unable to download updates and new packages, preventing client systems from obtaining them. (CVE-2012-1145) All users of Red Hat Network Satellite are advised to upgrade to these updated packages, which correct this issue. For this update to take effect, Red Hat Network Satellite must be restarted. Refer to the Solution section for details. 4. Solution: Before applying this update, make sure all previously-released errata relevant to your system have been applied. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/knowledge/articles/11258 Run the following command to restart the Red Hat Network Satellite server: # rhn-satellite restart 5.
