Red Hat Security Advisory

 

Synopsis: Moderate: java-1.6.0-openjdk security update

Advisory ID: RHSA-2011:0176-01

Product: Red Hat Enterprise Linux

Advisory URL: https://rhn.redhat.com/errata/RHSA-2011-0176.html

Issue date: 2011-01-25

CVE Names: CVE-2010-3860 CVE-2010-4351

=====================================================================

 

1. Summary:

 

Updated java-1.6.0-openjdk packages that fix two security issues are now

available for Red Hat Enterprise Linux 5.

 

The Red Hat Security Response Team has rated this update as having moderate

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 javaws command can be used to

launch Java Web Start applications.

 

A public static field declaration allowed untrusted JNLP (Java Network

Launching Protocol) applications to read privileged data. A remote attacker

could directly or indirectly read the values of restricted system

properties, such as "user.name", "user.home", and "java.home", which

untrusted applications should not be allowed to read. (CVE-2010-3860)

 

It was found that JNLPSecurityManager could silently return without

throwing an exception when permission was denied. If the javaws command was

used to launch a Java Web Start application that relies on this exception

being thrown, it could result in that application being run with elevated

privileges, allowing it to bypass security manager restrictions and gain

access to privileged functionality. (CVE-2010-4351)

 

Note: The RHSA-2010:0339 java-1.6.0-openjdk update installed javaws by

mistake. As part of the fixes for CVE-2010-3860 and CVE-2010-4351, this

update removes javaws.

 

Red Hat would like to thank the TippingPoint Zero Day Initiative project

for reporting CVE-2010-4351. The original issue reporter wishes to stay

anonymous.

 

This erratum also upgrades the OpenJDK package to IcedTea6 1.7.7. 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.
