Synopsis: Moderate: java-1.6.0-openjdk security update
Issue Date: 2011-01-25
CVE Numbers: CVE-2010-3860
CVE-2010-4351
—
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.
