Oracle Linux 5 / 6 : java-1.6.0-openjdk (ELSA-2014-0408)
Critical Nessus Plugin ID 73584
SynopsisThe remote Oracle Linux host is missing one or more security updates.
DescriptionFrom Red Hat Security Advisory 2014:0408 :
Updated java-1.6.0-openjdk packages that fix various security issues and one bug 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.
The java-1.6.0-openjdk packages provide the OpenJDK 6 Java Runtime Environment and the OpenJDK 6 Java Software Development Kit.
An input validation flaw was discovered in the medialib library in the 2D component. A specially crafted image could trigger Java Virtual Machine memory corruption when processed. A remote attacker, or an untrusted Java application or applet, could possibly use this flaw to execute arbitrary code with the privileges of the user running the Java Virtual Machine. (CVE-2014-0429)
Multiple flaws were discovered in the Hotspot and 2D components in OpenJDK. An untrusted Java application or applet could use these flaws to trigger Java Virtual Machine memory corruption and possibly bypass Java sandbox restrictions. (CVE-2014-0456, CVE-2014-2397, CVE-2014-2421)
Multiple improper permission check issues were discovered in the Libraries component in OpenJDK. An untrusted Java application or applet could use these flaws to bypass Java sandbox restrictions.
Multiple improper permission check issues were discovered in the AWT, JAX-WS, JAXB, Libraries, and Sound components in OpenJDK. An untrusted Java application or applet could use these flaws to bypass certain Java sandbox restrictions. (CVE-2014-2412, CVE-2014-0451, CVE-2014-0458, CVE-2014-2423, CVE-2014-0452, CVE-2014-2414, CVE-2014-0446, CVE-2014-2427)
Multiple flaws were identified in the Java Naming and Directory Interface (JNDI) DNS client. These flaws could make it easier for a remote attacker to perform DNS spoofing attacks. (CVE-2014-0460)
It was discovered that the JAXP component did not properly prevent access to arbitrary files when a SecurityManager was present. This flaw could cause a Java application using JAXP to leak sensitive information, or affect application availability. (CVE-2014-2403)
It was discovered that the Security component in OpenJDK could leak some timing information when performing PKCS#1 unpadding. This could possibly lead to the disclosure of some information that was meant to be protected by encryption. (CVE-2014-0453)
It was discovered that the fix for CVE-2013-5797 did not properly resolve input sanitization flaws in javadoc. When javadoc documentation was generated from an untrusted Java source code and hosted on a domain not controlled by the code author, these issues could make it easier to perform cross-site scripting (XSS) attacks.
An insecure temporary file use flaw was found in the way the unpack200 utility created log files. A local attacker could possibly use this flaw to perform a symbolic link attack and overwrite arbitrary files with the privileges of the user running unpack200. (CVE-2014-1876)
This update also fixes the following bug :
* The OpenJDK update to IcedTea version 1.13 introduced a regression related to the handling of the jdk_version_info variable. This variable was not properly zeroed out before being passed to the Java Virtual Machine, resulting in a memory leak in the java.lang.ref.Finalizer class. This update fixes this issue, and memory leaks no longer occur. (BZ#1085373)
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.
SolutionUpdate the affected java-1.6.0-openjdk packages.
