Description

LSAC(v2)
The java-1.6.0-openjdk packages provide the OpenJDK 6 Java Runtime Environment and the OpenJDK 6 Java Software Development Kit. 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) The CVE-2014-6512 was discovered by Florian Weimer of Red Hat Product Security. This update also fixes the following bug: * The TLS/SSL implementation in OpenJDK previously failed to handle Diffie-Hellman (DH) keys with more than 1024 bits. This caused client applications using JSSE to fail to establish TLS/SSL connections to servers using larger DH keys during the connection handshake. This update adds support for DH keys with size up to 2048 bits. (BZ#1148309) All users of java-1.6.0-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.
