An update for java-1.7.0-ibm is now available for Red Hat Enterprise Linux 5 Supplementary.

Red Hat Product Security has rated this update as having a security impact of Critical. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

IBM Java SE version 7 includes the IBM Java Runtime Environment and the IBM Java Software Development Kit.

This update upgrades IBM Java SE 7 to version 7 SR9-FP60.

Security Fix(es) :

* This update fixes multiple vulnerabilities in the IBM Java Runtime Environment and the IBM Java Software Development Kit. Further information about these flaws can be found on the IBM Java Security alerts page, listed in the References section. (CVE-2016-5542, CVE-2016-5554, CVE-2016-5556, CVE-2016-5573, CVE-2016-5597)

Several vulnerabilities have been discovered in OpenJDK, an implementation of the Oracle Java platform, resulting in information disclosure, denial of service and arbitrary code execution.

For Debian 7 'Wheezy', these problems have been fixed in version 7u111-2.6.7-2~deb7u1.

We recommend that you upgrade your openjdk-7 packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Security Fix(es) :

  - It was discovered that the Hotspot component of OpenJDK     did not properly check arguments of the     System.arraycopy() function in certain cases. An     untrusted Java application or applet could use this flaw     to corrupt virtual machine's memory and completely     bypass Java sandbox restrictions. (CVE-2016-5582)

  - It was discovered that the Hotspot component of OpenJDK     did not properly check received Java Debug Wire Protocol     (JDWP) packets. An attacker could possibly use this flaw     to send debugging commands to a Java program running     with debugging enabled if they could make victim's     browser send HTTP requests to the JDWP port of the     debugged application. (CVE-2016-5573)

  - It was discovered that the Libraries component of     OpenJDK did not restrict the set of algorithms used for     Jar integrity verification. This flaw could allow an     attacker to modify content of the Jar file that used     weak signing key or hash algorithm. (CVE-2016-5542)

Note: After this update, MD2 hash algorithm and RSA keys with less than 1024 bits are no longer allowed to be used for Jar integrity verification by default. MD5 hash algorithm is expected to be disabled by default in the future updates. A newly introduced security property jdk.jar.disabledAlgorithms can be used to control the set of disabled algorithms.

  - A flaw was found in the way the JMX component of OpenJDK     handled classloaders. An untrusted Java application or     applet could use this flaw to bypass certain Java     sandbox restrictions. (CVE-2016-5554)

  - A flaw was found in the way the Networking component of     OpenJDK handled HTTP proxy authentication. A Java     application could possibly expose HTTPS server     authentication credentials via a plain text network     connection to an HTTP proxy if proxy asked for     authentication. (CVE-2016-5597)

Note: After this update, Basic HTTP proxy authentication can no longer be used when tunneling HTTPS connection through an HTTP proxy. Newly introduced system properties jdk.http.auth.proxying.disabledSchemes and jdk.http.auth.tunneling.disabledSchemes can be used to control which authentication schemes can be requested by an HTTP proxy when proxying HTTP and HTTPS connections respectively.

The version of Java SDK installed on the remote AIX host is affected by multiple vulnerabilities in the following subcomponents :

  - An unspecified flaw exists in the Libraries subcomponent     that allows an unauthenticated, remote attacker to     impact integrity. (CVE-2016-5542)

  - An unspecified flaw exists in the JMX subcomponent that     allows an unauthenticated, remote attacker to impact     integrity. (CVE-2016-5554)

  - An unspecified flaw exists in the 2D subcomponent that     allows an unauthenticated, remote attacker to execute     arbitrary code. (CVE-2016-5556)

  - An unspecified flaw exists in the AWT subcomponent that     allows an unauthenticated, remote attacker to execute     arbitrary code. (CVE-2016-5568)

  - An unspecified flaw exists in the Networking     subcomponent that allows an unauthenticated, remote     attacker to disclose sensitive information.
    (CVE-2016-5597)

The version of Oracle Java SE installed on the remote host is prior to 6 Update 131, 7 Update 121, or 8 Update 112 and is affected by multiple vulnerabilities :

 - An unspecified flaw exists related to the Libraries subcomponent.  This may allow a context-dependent attacker to have an impact on integrity.  No further details have been provided by the vendor.  (CVE-2016-5542)
 - A flaw exists in 'share/classes/com/sun/jmx/remote/util/ClassLoaderWithRepository.java' related to improper classloader consistency checks.  This may allow a context-dependent attacker to bypass certain Java sandbox restrictions. (CVE-2016-5554)
 - An unspecified flaw exists related to the 2D subcomponent.  This may allow a context-dependent attacker to execute arbitrary code.  No further details have been provided by the vendor. (CVE-2016-5556)
 - A flaw exists related to the AWT subcomponent.  This may allow a context-dependent attacker to execute arbitrary code.  No further details have been provided by the vendor. (CVE-2016-5568)
 - An unspecified flaw exists related to the hotspot subcomponent.  This may allow a context-dependent attacker to execute arbitrary code.  No further details have been provided by the vendor. (CVE-2016-5573)
 - A flaw exists in 'cpu/sparc/vm/c1_LIRAssembler_sparc.cpp' and 'cpu/x86/vm/c1_LIRAssembler_x86.cpp'.  The issue is triggered when handling calls to the 'System.arraycopy()' method due to missing type checks.  This may allow a context-dependent attacker to bypass Java sandbox restrictions.  (CVE-2016-5582)
 - An unspecified flaw exists related to the Networking subcomponent.  This may allow a context-dependent attacker to gain access to potentially sensitive information.  No further details have been provided by the vendor. (CVE-2016-5597)
