Updated java-1.7.0-openjdk packages that fix multiple security issues are now available for Red Hat Enterprise Linux 6 and 7

Solution

Before applying this update, make sure all previously released errata relevant to your system have been applied.

Summary

The java-1.7.0-openjdk packages provide the OpenJDK 7 Java Runtime Environment and the OpenJDK 7 Java Software Development Kit.
An off-by-one flaw, leading to a buffer overflow, was found in the font parsing code in the 2D component in OpenJDK. A specially crafted font file could possibly cause the Java Virtual Machine to execute arbitrary code, allowing an untrusted Java application or applet to bypass Java sandbox restrictions. (CVE-2015-0469)
A flaw was found in the way the Hotspot component in OpenJDK handled phantom references. An untrusted Java application or applet could use this flaw to corrupt the Java Virtual Machine memory and, possibly, execute arbitrary code, bypassing Java sandbox restrictions. (CVE-2015-0460)
A flaw was found in the way the JSSE component in OpenJDK parsed X.509 certificate options. A specially crafted certificate could cause JSSE to raise an exception, possibly causing an application using JSSE to exit unexpectedly. (CVE-2015-0488)
A flaw was discovered in the Beans component in OpenJDK. An untrusted Java application or applet could use this flaw to bypass certain Java sandbox restrictions. (CVE-2015-0477)
A directory traversal flaw was found in the way the jar tool extracted JAR archive files. A specially crafted JAR archive could cause jar to overwrite arbitrary files writable by the user running jar when the archive was extracted. (CVE-2005-1080, CVE-2015-0480)
It was found that the RSA implementation in the JCE component in OpenJDK did not follow recommended practices for implementing RSA signatures. (CVE-2015-0478)
The CVE-2015-0478 issue was discovered by Florian Weimer of Red Hat Product Security.
Note: If the web browser plug-in provided by the icedtea-web package was installed, the issues exposed via Java applets could have been exploited without user interaction if a user visited a malicious website.
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.
