(RHSA-2011:0434) Moderate: security update for Red Hat Network Satellite

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.
