Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

Updated spacewalk-backend packages that fix one security issue are now
available for Red Hat Network Satellite 5.4 on Red Hat Enterprise
Linux 6.

The Red Hat Security Response Team 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 Network (RHN) 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. (The NULL organization stores packages synced from RHN
Hosted.) 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 (/var/) 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. (CVE-2012-1145)

All users of Red Hat Network Satellite are advised to upgrade to these
updated packages, which correct this issue. For this update to take
effect, Red Hat Network Satellite must be restarted. Refer to the
Solution section for details.
