(RHSA-2015:0216) Moderate: Red Hat JBoss Enterprise Application Platform 6.3.3 update

Red Hat JBoss Enterprise Application Platform 6 is a platform for Java
applications based on JBoss Application Server 7.

It was found that the RESTEasy DocumentProvider did not set the
external-parameter-entities and external-general-entities features
appropriately, thus allowing external entity expansion. A remote attacker
able to send XML requests to a RESTEasy endpoint could use this flaw to
read files accessible to the user running the application server, and
potentially perform other more advanced XML eXternal Entity (XXE) attacks.
(CVE-2014-7839)

It was discovered that the Role Based Access Control (RBAC) implementation
did not sufficiently verify all authorization conditions that are required
by the Maintainer role to perform certain administrative actions.
An authenticated user with the Maintainer role could use this flaw to add,
modify, or undefine a limited set of attributes and their values, which
otherwise cannot be written to. (CVE-2014-7849)

It was discovered that the JBoss Application Server (WildFly) JacORB
subsystem incorrectly assigned socket-binding-ref sensitivity
classification for the security-domain attribute. An authenticated user
with a role that has access to attributes with socket-binding-ref and not
security-domain-ref sensitivity classification could use this flaw to
access sensitive information present in the security-domain attribute.
(CVE-2014-7853)

It was found that when processing undefined security domains, the
org.jboss.security.plugins.mapping.JBossMappingManager implementation would
fall back to the default security domain if it was available. A user with
valid credentials in the defined default domain, with a role that is valid
in the expected application domain, could perform actions that were
otherwise not available to them. When using the SAML2 STS Login Module,
JBossMappingManager exposed this issue due to the PicketLink Trust
SecurityActions implementation using a hardcoded default value when
defining the context. (CVE-2014-7827)

It was discovered that under specific conditions the conversation state
information stored in a thread-local variable was not sanitized correctly
when the conversation ended. This could lead to a race condition that could
potentially expose sensitive information from a previous conversation to
the current conversation. (CVE-2014-8122)

Red Hat would like to thank Rune Steinseth of JProfessionals for reporting
the CVE-2014-8122 issue. The CVE-2014-7849 and CVE-2014-7853 issues were
discovered by Darran Lofthouse of the Red Hat JBoss Enterprise Application
Platform Team, and the CVE-2014-7827 issue was discovered by Ondra Lukas of
the Red Hat Quality Engineering Team.

This release serves as a replacement for Red Hat JBoss Enterprise
Application Platform 6.3.2, and includes bug fixes and enhancements.
Documentation for these changes is available from the link in the
References section.

All users of Red Hat JBoss Enterprise Application Platform 6.3 on Red Hat
Enterprise Linux 6 are advised to upgrade to these updated packages.
The JBoss server process must be restarted for the update to take effect.
