Scientific Linux Security Update : java-1.6.0-openjdk on SL5.x i386/x86_64
Medium Nessus Plugin ID 60942
SynopsisThe remote Scientific Linux host is missing one or more security updates.
DescriptionA 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.
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.
Note: The previous 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.
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 running instances of OpenJDK Java must be restarted for the update to take effect.
SolutionUpdate the affected packages.
