Scientific Linux Security Update : java-1.7.0-openjdk on SL5.x i386/x86_64

Synopsis :

The remote Scientific Linux host is missing one or more security

Description :

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.

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)

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.

All running instances of OpenJDK Java must be restarted for the update
to take effect.
