RHSA-2013:0245 - Security Advisory

Topic

Updated java-1.6.0-openjdk packages that fix several security issues are
now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having critical
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.

Description

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

Multiple improper permission check issues were discovered in the AWT,
CORBA, JMX, and Libraries components in OpenJDK. An untrusted Java
application or applet could use these flaws to bypass Java sandbox
restrictions. (CVE-2013-0442, CVE-2013-0445, CVE-2013-0441, CVE-2013-1475,
CVE-2013-1476, CVE-2013-0429, CVE-2013-0450, CVE-2013-0425, CVE-2013-0426,
CVE-2013-0428)

Multiple flaws were found in the way image parsers in the 2D and AWT
components handled image raster parameters. A specially-crafted image could
cause Java Virtual Machine memory corruption and, possibly, lead to
arbitrary code execution with the virtual machine privileges.
(CVE-2013-1478, CVE-2013-1480)

A flaw was found in the AWT component's clipboard handling code. An
untrusted Java application or applet could use this flaw to access
clipboard data, bypassing Java sandbox restrictions. (CVE-2013-0432)

The default Java security properties configuration did not restrict access
to certain com.sun.xml.internal packages. An untrusted Java application or
applet could use this flaw to access information, bypassing certain Java
sandbox restrictions. This update lists the whole package as restricted.
(CVE-2013-0435)

Multiple improper permission check issues were discovered in the Libraries,
Networking, and JAXP components. An untrusted Java application or applet
could use these flaws to bypass certain Java sandbox restrictions.
(CVE-2013-0427, CVE-2013-0433, CVE-2013-0434)

It was discovered that the RMI component's CGIHandler class used user
inputs in error messages without any sanitization. An attacker could use
this flaw to perform a cross-site scripting (XSS) attack. (CVE-2013-0424)

It was discovered that the SSL/TLS implementation in the JSSE component
did not properly enforce handshake message ordering, allowing an unlimited
number of handshake restarts. A remote attacker could use this flaw to
make an SSL/TLS server using JSSE consume an excessive amount of CPU by
continuously restarting the handshake. (CVE-2013-0440)

It was discovered that the JSSE component did not properly validate
Diffie-Hellman public keys. An SSL/TLS client could possibly use this flaw
to perform a small subgroup attack. (CVE-2013-0443)

Note: If the web browser plug-in provided by the icedtea-web package was
installed, the issues exposed via Java applets could have been exploited
without user interaction if a user visited a malicious website.

This erratum also upgrades the OpenJDK package to IcedTea6 1.11.6. 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.

Solution

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
