java security update

CentOS Errata and Security Advisory CESA-2012:0730

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

Multiple flaws were discovered in the CORBA (Common Object Request Broker
Architecture) implementation in Java. A malicious Java application or
applet could use these flaws to bypass Java sandbox restrictions or modify
immutable object data. (CVE-2012-1711, CVE-2012-1719)

It was discovered that the SynthLookAndFeel class from Swing did not
properly prevent access to certain UI elements from outside the current
application context. A malicious Java application or applet could use this
flaw to crash the Java Virtual Machine, or bypass Java sandbox
restrictions. (CVE-2012-1716)

Multiple flaws were discovered in the font manager’s layout lookup
implementation. A specially-crafted font file could cause the Java Virtual
Machine to crash or, possibly, execute arbitrary code with the privileges
of the user running the virtual machine. (CVE-2012-1713)

Multiple flaws were found in the way the Java HotSpot Virtual Machine
verified the bytecode of the class file to be executed. A specially-crafted
Java application or applet could use these flaws to crash the Java Virtual
Machine, or bypass Java sandbox restrictions. (CVE-2012-1723,
CVE-2012-1725)

It was discovered that the Java XML parser did not properly handle certain
XML documents. An attacker able to make a Java application parse a
specially-crafted XML file could use this flaw to make the XML parser enter
an infinite loop. (CVE-2012-1724)

It was discovered that the Java security classes did not properly handle
Certificate Revocation Lists (CRL). CRL containing entries with duplicate
certificate serial numbers could have been ignored. (CVE-2012-1718)

It was discovered that various classes of the Java Runtime library could
create temporary files with insecure permissions. A local attacker could
use this flaw to gain access to the content of such temporary files.
(CVE-2012-1717)
