====================================================================
1. Summary:

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

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.

2. Relevant releases/architectures:

Red Hat Enterprise Linux (v. 5 server) - i386, x86_64
Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64

3. Description:

These packages provide the OpenJDK 6 Java Runtime Environment and the
OpenJDK 6 Software Development Kit. The Java Runtime Environment (JRE)
contains the software and tools that users need to run applications written
using the Java programming language.

A flaw was found in the way the TLS/SSL (Transport Layer Security/Secure
Sockets Layer) protocols handle session renegotiation. A man-in-the-middle
attacker could use this flaw to prefix arbitrary plain text to a client's
session (for example, an HTTPS connection to a website). This could force
the server to process an attacker's request as if authenticated using the
victim's credentials. (CVE-2009-3555)

This update disables renegotiation in the Java Secure Socket Extension
(JSSE) component. Unsafe renegotiation can be re-enabled using the
sun.security.ssl.allowUnsafeRenegotiation property. Refer to the following
Knowledgebase article for details:

A number of flaws have been fixed in the Java Virtual Machine (JVM) and in
various Java class implementations. These flaws could allow an unsigned
applet or application to bypass intended access restrictions.
(CVE-2010-0082, CVE-2010-0084, CVE-2010-0085, CVE-2010-0088, CVE-2010-0094)

An untrusted applet could access clipboard information if a drag operation
was performed over that applet's canvas. This could lead to an information
leak. (CVE-2010-0091)

The rawIndex operation incorrectly handled large values, causing the
corruption of internal memory structures, resulting in an untrusted applet
or application crashing. (CVE-2010-0092)

The System.arraycopy operation incorrectly handled large index values,
potentially causing array corruption in an untrusted applet or application.
(CVE-2010-0093)

Subclasses of InetAddress may incorrectly interpret network addresses,
allowing an untrusted applet or application to bypass network access
restrictions. (CVE-2010-0095)

In certain cases, type assignments could result in "non-exact" interface
types. This could be used to bypass type-safety restrictions.
(CVE-2010-0845)

A buffer overflow flaw in LittleCMS (embedded in OpenJDK) could cause an
untrusted applet or application using color profiles from untrusted sources
to crash. (CVE-2010-0838)

An input validation flaw was found in the JRE unpack200 functionality. An
untrusted applet or application could use this flaw to elevate its
privileges. (CVE-2010-0837)

Deferred calls to trusted applet methods could be granted incorrect
permissions, allowing an untrusted applet or application to extend its
privileges. (CVE-2010-0840)

A missing input validation flaw in the JRE could allow an attacker to crash
an untrusted applet or application. (CVE-2010-0848)

A flaw in Java2D could allow an attacker to execute arbitrary code with the
privileges of a user running an untrusted applet or application that uses
Java2D. (CVE-2010-0847)

Note: The flaws concerning applets in this advisory, CVE-2010-0082,
CVE-2010-0084, CVE-2010-0085, CVE-2010-0088, CVE-2010-0091, CVE-2010-0092,
CVE-2010-0093, CVE-2010-0094, CVE-2010-0095, CVE-2010-0837, CVE-2010-0838,
CVE-2010-0840, CVE-2010-0847, and CVE-2010-0848, can only be triggered in
java-1.6.0-openjdk by calling the "appletviewer" application.

This update also provides three defense in depth patches. (BZ#575745,
BZ#575861, BZ#575789)

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
