Red Hat Security Advisory 2012-0436-01 - Red Hat Network 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. 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 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.
