1. Summary:
Updated java-1.6.0-openjdk packages that fix several security issues are
now available for Red Hat Enterprise Linux 5.
The Red Hat Security Response Team has rated this update as having
important security impact. Common Vulnerability Scoring System (CVSS) base
scores, which give detailed severity ratings, are available for each
vulnerability from the CVE links in the References section.
2. Relevant releases/architectures:
Red Hat Enterprise Linux (v. 5 server) - i386, x86_64
Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64
3. Description:
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)
This erratum also upgrades the OpenJDK package to IcedTea6 1.10.8. Refer to
the NEWS file, linked to in the References, for further information.
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.
4. Solution:
Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
This update is available via the Red Hat Network. Details on how to
