Synopsis:          Critical: java-1.6.0-openjdk security update
Advisory ID:       RHSA-2013:0273-01
Product:           Red Hat Enterprise Linux
Advisory URL:      https://access.redhat.com/errata/RHSA-2013:0273.html
Issue date:        2013-02-20
CVE Names:         CVE-2013-0169 CVE-2013-1486 
====================================================================
1. Summary:

Updated java-1.6.0-openjdk packages that fix two 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.

2. Relevant releases/architectures:

Red Hat Enterprise Linux Desktop (v. 6) - i386, x86_64
Red Hat Enterprise Linux Desktop Optional (v. 6) - i386, x86_64
Red Hat Enterprise Linux HPC Node (v. 6) - x86_64
Red Hat Enterprise Linux HPC Node Optional (v. 6) - x86_64
Red Hat Enterprise Linux Server (v. 6) - i386, x86_64
Red Hat Enterprise Linux Server Optional (v. 6) - i386, x86_64
Red Hat Enterprise Linux Workstation (v. 6) - i386, x86_64
Red Hat Enterprise Linux Workstation Optional (v. 6) - i386, x86_64

3. Description:

These packages provide the OpenJDK 6 Java Runtime Environment and the
OpenJDK 6 Software Development Kit.

An improper permission check issue was discovered in the JMX component in
OpenJDK. An untrusted Java application or applet could use this flaw to
bypass Java sandbox restrictions. (CVE-2013-1486)

It was discovered that OpenJDK leaked timing information when decrypting
TLS/SSL protocol encrypted records when CBC-mode cipher suites were used.
A remote attacker could possibly use this flaw to retrieve plain text from
the encrypted packets by using a TLS/SSL server as a padding oracle.
(CVE-2013-0169)

Note: If the web browser plug-in provided by the icedtea-web package was
installed, CVE-2013-1486 could have been exploited without user interaction
if a user visited a malicious website.

This erratum also upgrades the OpenJDK package to IcedTea6 1.11.8. Refer to
the NEWS file, linked to in the References, for further information.

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.

4. Solution:

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

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
https://access.redhat.com/articles/11258

5. Bugs fixed (http://bugzilla.redhat.com/):

907589 - CVE-2013-0169 SSL/TLS: CBC padding timing attack (lucky-13)
913014 - CVE-2013-1486 OpenJDK: MBeanServer insufficient privilege restrictions (JMX, 8006446)
