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 Network Satellite (RHN Satellite) is a system management tool for Linux-based infrastructures. It allows for the provisioning, remote management and monitoring of multiple Linux deployments with a single, centralized tool. RHN Satellite incorrectly exposed an obsolete XML-RPC API for configuring package group (comps.xml) files for channels. An authenticated user could use this flaw to gain access to arbitrary files accessible to the RHN Satellite server process, and prevent clients from performing certain yum operations. (CVE-2010-1171) A flaw was found in the way RHN Satellite rewrote certain URLs. An unauthenticated user could use a specially-crafted HTTP request to obtain sensitive information about the host system RHN Satellite was running on. They could also use RHN Satellite as a distributed denial of service tool, forcing it to connect to an arbitrary service at an arbitrary IP address via a specially-crafted HTTP request. (CVE-2009-0788) Note: Refer to the Solution section below for manual steps that may be required to fully address the CVE-2009-0788 issue. Users of RHN Satellite 5.3 and 5.4 are advised to upgrade to these updated packages, which contain backported patches to correct these issues. The RHN Satellite server must be restarted ("rhn-satellite restart") for this update to take effect.
