Multiple vulnerabilities in Oracle Java 7 before Update 11 allow remote attackers to execute arbitrary code by (1) using the public getMBeanInstantiator method in the JmxMBeanServer class to obtain a reference to a private MBeanInstantiator object, then retrieving arbitrary Class references using the findClass method, and (2) using the Reflection API with recursion in a way that bypasses a security check by the java.lang.invoke.MethodHandles.Lookup.checkSecurityManager method due to the inability of the sun.reflect.Reflection.getCallerClass method to skip frames related to the new reflection API, as exploited in the wild in January 2013, as demonstrated by Blackhole and Nuclear Pack, and a different vulnerability than CVE-2012-4681 and CVE-2012-3174. NOTE: some parties have mapped the recursive Reflection API issue to CVE-2012-3174, but CVE-2012-3174 is for a different vulnerability whose details are not public as of 20130114. CVE-2013-0422 covers both the JMX/MBean and Reflection API issues. NOTE: it was originally reported that Java 6 was also vulnerable, but the reporter has retracted this claim, stating that Java 6 is not exploitable because the relevant code is called in a way that does not bypass security checks. NOTE: as of 20130114, a reliable third party has claimed that the findClass/MBeanInstantiator vector was not fixed in Oracle Java 7 Update 11. If there is still a vulnerable condition, then a separate CVE identifier might be created for the unfixed issue.

From Red Hat Security Advisory 2013:0165 :

Updated java-1.7.0-openjdk packages that fix two security issues are now available for Red Hat Enterprise Linux 5 and 6.

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.

These packages provide the OpenJDK 7 Java Runtime Environment and the OpenJDK 7 Software Development Kit.

Two improper permission check issues were discovered in the reflection API in OpenJDK. An untrusted Java application or applet could use these flaws to bypass Java sandbox restrictions. (CVE-2012-3174, CVE-2013-0422)

This erratum also upgrades the OpenJDK package to IcedTea7 2.3.4.
Refer to the NEWS file, linked to in the References, for further information.

All users of java-1.7.0-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.

Updated java-1.7.0-openjdk packages fix security vulnerabilities :

Two improper permission check issues were discovered in the reflection API in OpenJDK. An untrusted Java application or applet could use these flaws to bypass Java sandbox restrictions (CVE-2012-3174, CVE-2013-0422).

Multiple improper permission check issues were discovered in the AWT, CORBA, JMX, Libraries, and Beans 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, CVE-2013-0444).

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 JMX, Libraries, Networking, and JAXP components. An untrusted Java application or applet could use these flaws to bypass certain Java sandbox restrictions (CVE-2013-0431, 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).

Multiple improper permission check issues were discovered in the JMX and Libraries components in OpenJDK. An untrusted Java application or applet could use these flaws to bypass Java sandbox restrictions (CVE-2013-1486, CVE-2013-1484).

An improper permission check issue was discovered in the Libraries component in OpenJDK. An untrusted Java application or applet could use this flaw to bypass certain Java sandbox restrictions (CVE-2013-1485).

It was discovered that OpenJDK leaked timing information when decrypting TLS/SSL protocol encrypted records when CBC-mode cipher suites were used. A remote attacker could possibly use this flaw to retrieve plain text from the encrypted packets by using a TLS/SSL server as a padding oracle (CVE-2013-0169).

An integer overflow flaw was found in the way the 2D component handled certain sample model instances. A specially crafted sample model instance could cause Java Virtual Machine memory corruption and, possibly, lead to arbitrary code execution with virtual machine privileges (CVE-2013-0809).

It was discovered that the 2D component did not properly reject certain malformed images. Specially crafted raster parameters could cause Java Virtual Machine memory corruption and, possibly, lead to arbitrary code execution with virtual machine privileges (CVE-2013-1493).

IBM Java 7 was updated to SR4, fixing various critical security issues and bugs.

All users of java-1.7.0-ibm are advised to upgrade to these updated packages, containing the IBM Java SE 7 SR4 release. All running instances of IBM Java must be restarted for the update to take effect.

The version of Oracle (formerly Sun) Java SE or Java for Business installed on the remote host is earlier than 7 Update 11 and is, therefore, potentially affected by the following security issues :

  - An unspecified issue exists in the Libraries     component. (CVE-2012-3174)

  - An error exists in the 'MBeanInstantiator.findClass'     method that could allow remote, arbitrary code execution.
    (CVE-2013-0422)

Note that, according the advisory, these issues apply to client deployments of Java only and can only be exploited through untrusted 'Java Web Start' applications and untrusted Java applets.

It was discovered that OpenJDK 7's security mechanism could be bypassed via Java applets. If a user were tricked into opening a malicious website, a remote attacker could exploit this to perform arbitrary code execution as the user invoking the program.

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