Multiple vulnerabilities has been discovered and corrected in
java-1.7.0-openjdk:

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 updated packages provides a solution for these security issues.
