Important: candlepin security update
Security Advisory: Important
Updated candlepin packages that fix one security issue are now available
for Red Hat Subscription Asset Manager.
The Red Hat Security Response Team has rated this update as having
important 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.
Candlepin is an open source entitlement management system. It tracks the
products which an owner has subscribed too, and allows the owner to consume
the subscriptions based on configurable business rules.
It was discovered that, by default, Candlepin enabled a very weak
authentication scheme if no setting was specified in the configuration
file. (CVE-2013-6439)
This issue was discovered by Adrian Likins of Red Hat.
Note: The configuration file as supplied by Subscription Asset Manager 1.2
and 1.3 had this unsafe authentication mode disabled; however, users who
have upgraded from Subscription Asset Manager 1.1 or earlier and who have
not added "candlepin.auth.trusted.enable = false" to the Candlepin
configuration will be affected by this issue.
Users of Subscription Asset Manager 1.0 or 1.1 who cannot upgrade
should add the following to "/etc/candlepin/candlepin.conf":
candlepin.auth.trusted.enable = false
candlepin.auth.trusted.enabled = false
Users of Subscription Asset Manager 1.2 or 1.3 who cannot upgrade should
only need to add:
candlepin.auth.trusted.enable = false
Installing this upgrade disables the unsafe authentication scheme unless
it is specifically enabled in the configuration.
Users of Red Hat Subscription Asset Manager are advised to upgrade to
these updated packages, which correct this issue. Candlepin must be
restarted for this update to take effect.
Before applying this update, make sure all previously released errata
relevant to your system have been applied.
