RHSA-2015:0957 - Security Advisory

Topic

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.

Description

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.
