MDVSA-2015:033: java-1.7.0-openjdk

Updated java-1.7.0 packages fix security vulnerabilities:

A flaw was found in the way the Hotspot component in OpenJDK verified
bytecode from the class files. An untrusted Java application or applet
could possibly use this flaw to bypass Java sandbox restrictions
(CVE-2014-6601).

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

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).

Note: This update disables SSL 3.0 by default to mitigate the POODLE
issue, also known as CVE-2014-3566. 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.
