=====================================================================
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.
It was discovered that Java2D did not properly check graphics rendering
objects before passing them to the native renderer. Malicious input, or an
untrusted Java application or applet could use this flaw to crash the Java
Virtual Machine (JVM), or bypass Java sandbox restrictions. (CVE-2012-0497)
It was discovered that the exception thrown on deserialization failure did
not always contain a proper identification of the cause of the failure. An
untrusted Java application or applet could use this flaw to bypass Java
sandbox restrictions. (CVE-2012-0505)
The AtomicReferenceArray class implementation did not properly check if
the array was of the expected Object[] type. A malicious Java application
or applet could use this flaw to bypass Java sandbox restrictions.
(CVE-2011-3571)
It was discovered that the use of TimeZone.setDefault() was not restricted
by the SecurityManager, allowing an untrusted Java application or applet to
set a new default time zone, and hence bypass Java sandbox restrictions.
(CVE-2012-0503)
The HttpServer class did not limit the number of headers read from HTTP
requests. A remote attacker could use this flaw to make an application
using HttpServer use an excessive amount of CPU time via a
specially-crafted request. This update introduces a header count limit
controlled using the sun.net.httpserver.maxReqHeaders property. The default
value is 200. (CVE-2011-5035)
The Java Sound component did not properly check buffer boundaries.
Malicious input, or an untrusted Java application or applet could use this
flaw to cause the Java Virtual Machine (JVM) to crash or disclose a portion
of its memory. (CVE-2011-3563)
A flaw was found in the AWT KeyboardFocusManager that could allow an
untrusted Java application or applet to acquire keyboard focus and possibly
steal sensitive information. (CVE-2012-0502)
It was discovered that the CORBA (Common Object Request Broker
Architecture) implementation in Java did not properly protect repository
identifiers on certain CORBA objects. This could have been used to modify
immutable object data. (CVE-2012-0506)
An off-by-one flaw, causing a stack overflow, was found in the unpacker for
ZIP files. A specially-crafted ZIP archive could cause the Java Virtual
Machine (JVM) to crash when opened. (CVE-2012-0501)
This erratum also upgrades the OpenJDK package to IcedTea6 1.10.6. 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.
