SynopsisThe remote Red Hat host is missing one or more security updates.
DescriptionUpdated java-1.7.0-openjdk packages that fix several security issues are now available for Red Hat Enterprise Linux 6.
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.
[Update 13 November 2012] The file list of this advisory was updated to move java-1.7.0-openjdk-devel from the optional repositories to the base repositories. Additionally, java-1.7.0-openjdk for the HPC Node variant was also moved (this package was already in the base repositories for other product variants). No changes have been made to the packages themselves.
These packages provide the OpenJDK 7 Java Runtime Environment and the OpenJDK 7 Software Development Kit.
Multiple improper permission check issues were discovered in the Beans, Libraries, Swing, and JMX components in OpenJDK. An untrusted Java application or applet could use these flaws to bypass Java sandbox restrictions. (CVE-2012-5086, CVE-2012-5087, CVE-2012-5088, CVE-2012-5084, CVE-2012-5089)
The default Java security properties configuration did not restrict access to certain com.sun.org.glassfish packages. An untrusted Java application or applet could use these flaws to bypass Java sandbox restrictions. This update lists those packages as restricted.
Multiple improper permission check issues were discovered in the Scripting, JMX, Concurrency, Libraries, and Security components in OpenJDK. An untrusted Java application or applet could use these flaws to bypass certain Java sandbox restrictions. (CVE-2012-5068, CVE-2012-5071, CVE-2012-5069, CVE-2012-5073, CVE-2012-5072)
It was discovered that java.util.ServiceLoader could create an instance of an incompatible class while performing provider lookup. An untrusted Java application or applet could use this flaw to bypass certain Java sandbox restrictions. (CVE-2012-5079)
It was discovered that the Java Secure Socket Extension (JSSE) SSL/TLS implementation did not properly handle handshake records containing an overly large data length value. An unauthenticated, remote attacker could possibly use this flaw to cause an SSL/TLS server to terminate with an exception. (CVE-2012-5081)
It was discovered that the JMX component in OpenJDK could perform certain actions in an insecure manner. An untrusted Java application or applet could possibly use these flaws to disclose sensitive information. (CVE-2012-5070, CVE-2012-5075)
A bug in the Java HotSpot Virtual Machine optimization code could cause it to not perform array initialization in certain cases. An untrusted Java application or applet could use this flaw to disclose portions of the virtual machine's memory. (CVE-2012-4416)
It was discovered that the SecureRandom class did not properly protect against the creation of multiple seeders. An untrusted Java application or applet could possibly use this flaw to disclose sensitive information. (CVE-2012-5077)
It was discovered that the java.io.FilePermission class exposed the hash code of the canonicalized path name. An untrusted Java application or applet could possibly use this flaw to determine certain system paths, such as the current working directory.
This update disables Gopher protocol support in the java.net package by default. Gopher support can be enabled by setting the newly introduced property, 'jdk.net.registerGopherProtocol', to true.
This erratum also upgrades the OpenJDK package to IcedTea7 2.3.3.
Refer to the NEWS file, linked to in the References, for further information.
All users of java-1.7.0-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.
SolutionUpdate the affected packages.
