Updated java-1.7.0-openjdk packages that fix multiple security issues and
one bug are now available for Red Hat Enterprise Linux 6 and 7.
Red Hat Product Security has rated this update as having Important security
impact. Common Vulnerability Scoring System (CVSS) base scores, which give
detailed severity ratings, are available for each vulnerability from the
CVE links in the References section.
The java-1.7.0-openjdk packages provide the OpenJDK 7 Java Runtime
Environment and the OpenJDK 7 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.
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
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.
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-1.7.0-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.
