Updated java-1.7.0-openjdk packages that fix several security issues arenow available for Red Hat Enterprise Linux 5 and 6.The Red Hat Security Response Team has rated this update as havingimportant security impact. Common Vulnerability Scoring System basescores, which give detailed severity ratings, are available for eachvulnerability from the CVE links in the References section. These packages provide the OpenJDK 7 Java Runtime Environment and theOpenJDK 7 Software Development Kit.Multiple improper permission check issues were discovered in the AWT,CORBA, JMX, Libraries, and Beans components in OpenJDK. An untrusted Javaapplication or applet could use these flaws to bypass Java sandboxrestrictions. Multiple flaws were found in the way image parsers in the 2D and AWTcomponents handled image raster parameters. A specially-crafted image couldcause Java Virtual Machine memory corruption and, possibly, lead toarbitrary code execution with the virtual machine privileges.A flaw was found in the AWT component's clipboard handling code. Anuntrusted Java application or applet could use this flaw to accessclipboard data, bypassing Java sandbox restrictions. The default Java security properties configuration did not restrict accessto certain com.sun.xml.internal packages. An untrusted Java application orapplet could use this flaw to access information, bypassing certain Javasandbox restrictions. This update lists the whole package as restricted.Multiple improper permission check issues were discovered in the JMX,Libraries, Networking, and JAXP components. An untrusted Java applicationor applet could use these flaws to bypass certain Java sandboxrestrictions. It was discovered that the RMI component's CGIHandler class used userinputs in error messages without any sanitization. An attacker could usethis flaw to perform a cross-site scripting attack. It was discovered that the SSL/TLS implementation in the JSSE componentdid not properly enforce handshake message ordering, allowing an unlimitednumber of handshake restarts. A remote attacker could use this flaw tomake an SSL/TLS server using JSSE consume an excessive amount of CPU bycontinuously restarting the handshake. It was discovered that the JSSE component did not properly validateDiffie-Hellman public keys. An SSL/TLS client could possibly use this flawto perform a small subgroup attack. This erratum also upgrades the OpenJDK package to IcedTea7 2.3.5. Refer tothe NEWS file, linked to in the References, for further information.All users of java-1.7.0-openjdk are advised to upgrade to these updatedpackages, which resolve these issues. All running instances of OpenJDK Javamust be restarted for the update to take effect.
