Red Hat Security Advisory
Synopsis: Moderate: Red Hat JBoss Data Virtualization security and bug fix update
Advisory ID: RHSA-2017:0272-01
Product: Red Hat JBoss Data Virtualization
Advisory URL: https://rhn.redhat.com/errata/RHSA-2017-0272.html
Issue date: 2017-02-14
CVE Names: CVE-2016-2175 CVE-2016-4434 CVE-2016-6814
=====================================================================
1. Summary:
An update is now available for Red Hat JBoss Data Virtualization.
Red Hat Product Security has rated this update as having a security impact
of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which
gives a detailed severity rating, is available for each vulnerability from
the CVE link(s) in the References section.
2. Description:
Red Hat JBoss Data Virtualization is a lean data integration solution that
provides easy, real-time, and unified data access across disparate sources
to multiple applications and users. JBoss Data Virtualization makes data
spread across physically distinct systems - such as multiple databases, XML
files, and even Hadoop systems - appear as a set of tables in a local
database.
This release of Red Hat JBoss Data Virtualization 6.3 Update 4 serves as a
replacement for Red Hat JBoss Data Virtualization 6.3 Update 3, and
includes bug fixes and enhancements, which are documented in the Release
Notes document linked to in the References.
Security Fix(es):
* It was found that a flaw in apache groovy library allows remote code
execution wherever deserialization occurs in the application. It is
possible for an attacker to craft a special serialized object that will
execute code directly when deserialized. All applications which rely on
serialization and do not isolate the code which deserializes objects are
subject to this vulnerability. (CVE-2016-6814)
* It was found that the parsing of XMP and other XML formats in PDF by
Apache PDFBox would expand entity references. A remote, unauthenticated
attacker could use this flaw to read files accessible to the user running
the application server, and potentially perform other more advanced XXE
attacks. (CVE-2016-2175)
* It was found that the parsing of OOXML, XMP in PDF, and some other file
formats by Apache Tika would expand entity references. A remote,
unauthenticated attacker could use this flaw to read files accessible to
the user running the application server, and potentially perform other more
advanced XXE attacks. (CVE-2016-4434)
3. Solution:
Before applying the update, back up your existing Red Hat JBoss Data
Virtualization installation (including its databases, applications,
configuration files, and so on).
Note that it is recommended to halt the Red Hat JBoss Data Virtualization
server by stopping the JBoss Application Server process before installing
this update, and then after installing the update, restart the Red Hat
JBoss Data Virtualization server by starting the JBoss Application Server
process.
The References section of this erratum contains a download link (you must
log in to download the update).
