3. Description:

The java-1.8.0-openjdk packages provide the OpenJDK 8 Java Runtime
Environment and the OpenJDK 8 Java Software Development Kit.

Multiple flaws were found in the way the Hotspot component in OpenJDK
verified bytecode from the class files, and in the way this component
generated code for bytecode. An untrusted Java application or applet could
possibly use these flaws to bypass Java sandbox restrictions.
(CVE-2014-6601, CVE-2015-0437)

Multiple improper permission check issues were discovered in the JAX-WS,
Libraries, and RMI components in OpenJDK. An untrusted Java application or
applet could use these flaws to bypass Java sandbox restrictions.
(CVE-2015-0412, CVE-2014-6549, CVE-2015-0408)

A flaw was found in the way the Hotspot garbage collector handled phantom
references. An untrusted Java application or applet could use this flaw to
corrupt the Java Virtual Machine memory and, possibly, execute arbitrary
code, bypassing Java sandbox restrictions. (CVE-2015-0395)

A flaw was found in the way the DER (Distinguished Encoding Rules) decoder
in the Security component in OpenJDK handled negative length values. A
specially crafted, DER-encoded input could cause a Java application to
enter an infinite loop when decoded. (CVE-2015-0410)

A flaw was found in the way the SSL 3.0 protocol handled padding bytes when
decrypting messages that were encrypted using block ciphers in cipher block
chaining (CBC) mode. This flaw could possibly allow a man-in-the-middle
(MITM) attacker to decrypt portions of the cipher text using a padding
oracle attack. (CVE-2014-3566)

Note: This update disables SSL 3.0 by default to address this issue.
The jdk.tls.disabledAlgorithms security property can be used to re-enable
SSL 3.0 support if needed. For additional information, refer to the Red Hat
Bugzilla bug linked to in the References section.

It was discovered that the SSL/TLS implementation in the JSSE component in
OpenJDK failed to properly check whether the ChangeCipherSpec was received
during the SSL/TLS connection handshake. An MITM attacker could possibly
use this flaw to force a connection to be established without encryption
being enabled. (CVE-2014-6593)

An information leak flaw was found in the Swing component in OpenJDK. An
untrusted Java application or applet could use this flaw to bypass certain
Java sandbox restrictions. (CVE-2015-0407)

A NULL pointer dereference flaw was found in the MulticastSocket
implementation in the Libraries component of OpenJDK. An untrusted Java
application or applet could possibly use this flaw to bypass certain Java
sandbox restrictions. (CVE-2014-6587)

Multiple boundary check flaws were found in the font parsing code in the 2D
component in OpenJDK. A specially crafted font file could allow an
untrusted Java application or applet to disclose portions of the Java
Virtual Machine memory. (CVE-2014-6585, CVE-2014-6591)

Multiple insecure temporary file use issues were found in the way the
Hotspot component in OpenJDK created performance statistics and error log
files. A local attacker could possibly make a victim using OpenJDK
overwrite arbitrary files using a symlink attack. (CVE-2015-0383)

The CVE-2015-0383 issue was discovered by Red Hat.

All users of java-1.8.0-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.

4. Solution:

Before applying this update, make sure all previously released errata
relevant to your system have been applied.
