"Updated spacewalk packages that fix one security issue are now
available for Red Hat Satellite 5.7.

Red Hat Product Security 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.

Red Hat Satellite is a system 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 the RPC interface in Satellite would resolve
external entities, allowing an attacker to conduct XML External Entity
(XXE) attacks. A remote attacker could use this flaw to read files
accessible to the user running the Satellite server, and potentially
perform other more advanced XXE attacks. (CVE-2014-8162)

Red Hat would like to thank Travis Emmert for reporting this issue.

All spacewalk users are advised to upgrade to these updated packages,
which contain a backported patch to correct this issue."
