Description

These packages provide the OpenJDK 6 Java Runtime Environment and the
OpenJDK 6 Java Software Development Kit.

An input validation flaw was discovered in the font layout engine in the 2D
component. A specially crafted font file could trigger a Java Virtual
Machine memory corruption when processed. An untrusted Java application or
applet could possibly use this flaw to bypass Java sandbox restrictions.
(CVE-2013-5907)

Multiple improper permission check issues were discovered in the CORBA and
JNDI components in OpenJDK. An untrusted Java application or applet could
use these flaws to bypass Java sandbox restrictions. (CVE-2014-0428,
CVE-2014-0422)

Multiple improper permission check issues were discovered in the
Serviceability, Security, CORBA, JAAS, JAXP, and Networking components in
OpenJDK. An untrusted Java application or applet could use these flaws to
bypass certain Java sandbox restrictions. (CVE-2014-0373, CVE-2013-5878,
CVE-2013-5910, CVE-2013-5896, CVE-2013-5884, CVE-2014-0416, CVE-2014-0376,
CVE-2014-0368)

It was discovered that the Beans component did not restrict processing of
XML external entities. This flaw could cause a Java application using Beans
to leak sensitive information, or affect application availability.
(CVE-2014-0423)

It was discovered that the JSSE component could leak timing information
during the TLS/SSL handshake. This could possibly lead to a disclosure of
information about the used encryption keys. (CVE-2014-0411)

All users of java-1.6.0-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.
