Summary: Updated java-1.7.0-openjdk packages fix security vulnerabilities

Details: Multiple flaws were discovered in the Libraries, 2D, and Hotspot components in OpenJDK. An untrusted Java application or applet could use these flaws to bypass certain Java sandbox restrictions (CVE-2014-6506, CVE-2014-6531, CVE-2014-6502, CVE-2014-6511, CVE-2014-6504, CVE-2014-6519). It was discovered that the StAX XML parser in the JAXP component in OpenJDK performed expansion of external parameter entities even when external entity substitution was disabled. A remote attacker could use this flaw to perform XML eXternal Entity (XXE) attack against applications using the StAX parser to parse untrusted XML documents (CVE-2014-6517). It was discovered that the DatagramSocket implementation in OpenJDK failed to perform source address checks for packets received on a connected socket. A remote attacker could use this flaw to have their packets processed as if they were received from the expected source (CVE-2014-6512). It was discovered that the TLS/SSL implementation in the JSSE component in OpenJDK failed to properly verify the server identity during the renegotiation following session resumption, making it possible for malicious TLS/SSL servers to perform a Triple Handshake attack against clients using JSSE and client certificate authentication (CVE-2014-6457). It was discovered that the CipherInputStream class implementation in OpenJDK did not properly handle certain exceptions. This could possibly allow an attacker to affect the integrity of an encrypted stream handled by this class (CVE-2014-6558). This update is based on IcedTea version 2.5.3, which fixes these issues, as well as several others.
