RHSA-2013:0751 - Security Advisory

Topic

Updated java-1.7.0-openjdk packages that fix various security issues are
now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having critical
security impact. Common Vulnerability Scoring System (CVSS) base scores,
which give detailed severity ratings, are available for each vulnerability
from the CVE links in the References section.

Description

These packages provide the OpenJDK 7 Java Runtime Environment and the
OpenJDK 7 Software Development Kit.

Multiple flaws were discovered in the font layout engine in the 2D
component. An untrusted Java application or applet could possibly use these
flaws to trigger Java Virtual Machine memory corruption. (CVE-2013-1569,
CVE-2013-2383, CVE-2013-2384)

Multiple improper permission check issues were discovered in the Beans,
Libraries, JAXP, and RMI components in OpenJDK. An untrusted Java
application or applet could use these flaws to bypass Java sandbox
restrictions. (CVE-2013-1558, CVE-2013-2422, CVE-2013-2436, CVE-2013-1518,
CVE-2013-1557)

The previous default value of the java.rmi.server.useCodebaseOnly property
permitted the RMI implementation to automatically load classes from
remotely specified locations. An attacker able to connect to an application
using RMI could use this flaw to make the application execute arbitrary
code. (CVE-2013-1537)

Note: The fix for CVE-2013-1537 changes the default value of the property
to true, restricting class loading to the local CLASSPATH and locations
specified in the java.rmi.server.codebase property. Refer to Red Hat
Bugzilla bug 952387 for additional details.

The 2D component did not properly process certain images. An untrusted Java
application or applet could possibly use this flaw to trigger Java Virtual
Machine memory corruption. (CVE-2013-2420)

It was discovered that the Hotspot component did not properly handle
certain intrinsic frames, and did not correctly perform access checks and
MethodHandle lookups. An untrusted Java application or applet could
use these flaws to bypass Java sandbox restrictions. (CVE-2013-2431,
CVE-2013-2421, CVE-2013-2423)

It was discovered that JPEGImageReader and JPEGImageWriter in the ImageIO
component did not protect against modification of their state while
performing certain native code operations. An untrusted Java application or
applet could possibly use these flaws to trigger Java Virtual Machine
memory corruption. (CVE-2013-2429, CVE-2013-2430)

The JDBC driver manager could incorrectly call the toString() method in
JDBC drivers, and the ConcurrentHashMap class could incorrectly call the
defaultReadObject() method. An untrusted Java application or applet could
possibly use these flaws to bypass Java sandbox restrictions.
(CVE-2013-1488, CVE-2013-2426)

The sun.awt.datatransfer.ClassLoaderObjectInputStream class may incorrectly
invoke the system class loader. An untrusted Java application or applet
could possibly use this flaw to bypass certain Java sandbox restrictions.
(CVE-2013-0401)

Flaws were discovered in the Network component's InetAddress serialization,
and the 2D component's font handling. An untrusted Java application or
applet could possibly use these flaws to crash the Java Virtual Machine.
(CVE-2013-2417, CVE-2013-2419)

The MBeanInstantiator class implementation in the OpenJDK JMX component did
not properly check class access before creating new instances. An untrusted
Java application or applet could use this flaw to create instances of
non-public classes. (CVE-2013-2424)

It was discovered that JAX-WS could possibly create temporary files with
insecure permissions. A local attacker could use this flaw to access
temporary files created by an application using JAX-WS. (CVE-2013-2415)

Note: If the web browser plug-in provided by the icedtea-web package was
installed, the issues exposed via Java applets could have been exploited
without user interaction if a user visited a malicious website.

This erratum also upgrades the OpenJDK package to IcedTea7 2.3.9. Refer to
the NEWS file, linked to in the References, for further information.

All users of java-1.7.0-openjdk are advised to upgrade to these updated
packages, which resolve these issues. All running instances of OpenJDK Java
must be restarted for the update to take effect.

Solution

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
