Updated java-1.6.0-openjdk packages that fix various security issues are
now available for Red Hat Enterprise Linux 5 and 6.

The Red Hat Security Response Team has rated this update as having
important 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 6 Java Runtime Environment and the
OpenJDK 6 Software Development Kit.

Multiple flaws were discovered in the ImagingLib and the image attribute,
channel, layout and raster processing in the 2D component. An untrusted
Java application or applet could possibly use these flaws to trigger Java
Virtual Machine memory corruption. (CVE-2013-2470, CVE-2013-2471,
CVE-2013-2472, CVE-2013-2473, CVE-2013-2463, CVE-2013-2465, CVE-2013-2469)

Integer overflow flaws were found in the way AWT processed certain input.
An attacker could use these flaws to execute arbitrary code with the
privileges of the user running an untrusted Java applet or application.
(CVE-2013-2459)

Multiple improper permission check issues were discovered in the Sound and
JMX components in OpenJDK. An untrusted Java application or applet could
use these flaws to bypass Java sandbox restrictions. (CVE-2013-2448,
CVE-2013-2457, CVE-2013-2453)

Multiple flaws in the Serialization, Networking, Libraries and CORBA
components can be exploited by an untrusted Java application or applet to
gain access to potentially sensitive information. (CVE-2013-2456,
CVE-2013-2447, CVE-2013-2455, CVE-2013-2452, CVE-2013-2443, CVE-2013-2446)

It was discovered that the Hotspot component did not properly handle
out-of-memory errors. An untrusted Java application or applet could
possibly use these flaws to terminate the Java Virtual Machine.
(CVE-2013-2445)

It was discovered that the AWT component did not properly manage certain
resources and that the ObjectStreamClass of the Serialization component
did not properly handle circular references. An untrusted Java application
or applet could possibly use these flaws to cause a denial of service.
(CVE-2013-2444, CVE-2013-2450)

It was discovered that the Libraries component contained certain errors
related to XML security and the class loader. A remote attacker could
possibly exploit these flaws to bypass intended security mechanisms or
disclose potentially sensitive information and cause a denial of service.
(CVE-2013-2407, CVE-2013-2461)

It was discovered that JConsole did not properly inform the user when
establishing an SSL connection failed. An attacker could exploit this flaw
to gain access to potentially sensitive information. (CVE-2013-2412)

It was found that documentation generated by Javadoc was vulnerable to a
frame injection attack. If such documentation was accessible over a
network, and a remote attacker could trick a user into visiting a
specially-crafted URL, it would lead to arbitrary web content being
displayed next to the documentation. This could be used to perform a
phishing attack by providing frame content that spoofed a login form on
the site hosting the vulnerable documentation. (CVE-2013-1571)

It was discovered that the 2D component created shared memory segments with
insecure permissions. A local attacker could use this flaw to read or write
to the shared memory segment. (CVE-2013-1500)

Red Hat would like to thank US-CERT for reporting CVE-2013-1571, and Tim
Brown for reporting CVE-2013-1500. US-CERT acknowledges Oracle as the
original reporter of CVE-2013-1571.

All users of java-1.6.0-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.
