Available Exploits 


Updated java-1.6.0-openjdk packages that fix several security issues are now available for CentOS Linux 5. The CentOS 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 6 Java Runtime Environment and the OpenJDK 6 Software Development Kit. The Java Runtime Environment (JRE) contains the software and tools that users need to run applications written using the Java programming language. A flaw was found in the way the TLS/SSL (Transport Layer Security/Secure Sockets Layer) protocols handle session renegotiation. A man-in-the-middle attacker could use this flaw to prefix arbitrary plain text to a client's session (for example, an HTTPS connection to a website). This could force the server to process an attacker's request as if authenticated using the victim's credentials. (CVE-2009-3555) This update disables renegotiation in the Java Secure Socket Extension (JSSE) component. Unsafe renegotiation can be re-enabled using the property. Refer to the following Knowledgebase article for details: A number of flaws have been fixed in the Java Virtual Machine (JVM) and in various Java class implementations. These flaws could allow an unsigned applet or application to bypass intended access restrictions. (CVE-2010-0082, CVE-2010-0084, CVE-2010-0085, CVE-2010-0088, CVE-2010-0094) An untrusted applet could access clipboard information if a drag operation was performed over that applet's canvas. This could lead to an information leak. (CVE-2010-0091) The rawIndex operation incorrectly handled large values, causing the corruption of internal memory structures, resulting in an untrusted applet or application crashing. (CVE-2010-0092) The System.arraycopy operation incorrectly handled large index values, potentially causing array corruption in an untrusted applet or application. (CVE-2010-0093) Subclasses of InetAddress may incorrectly interpret network addresses, allowing an untrusted applet or application to bypass network access restrictions. (CVE-2010-0095) In certain cases, type assignments could result in "non-exact" interface types. This could be used to bypass type-safety restrictions. (CVE-2010-0845) A buffer overflow flaw in LittleCMS (embedded in OpenJDK) could cause an untrusted applet or application using color profiles from untrusted sources to crash. (CVE-2010-0838) An input validation flaw was found in the JRE unpack200 functionality. An untrusted applet or application could use this flaw to elevate its privileges. (CVE-2010-0837) Deferred calls to trusted applet methods could be granted incorrect permissions, allowing an untrusted applet or application to extend its privileges. (CVE-2010-0840) A missing input validation flaw in the JRE could allow an attacker to crash an untrusted applet or application. (CVE-2010-0848) A flaw in Java2D could allow an attacker to execute arbitrary code with the privileges of a user running an untrusted applet or application that uses Java2D. (CVE-2010-0847) Note: The flaws concerning applets in this advisory, CVE-2010-0082, CVE-2010-0084, CVE-2010-0085, CVE-2010-0088, CVE-2010-0091, CVE-2010-0092, CVE-2010-0093, CVE-2010-0094, CVE-2010-0095, CVE-2010-0837, CVE-2010-0838, CVE-2010-0840, CVE-2010-0847, and CVE-2010-0848, can only be triggered in java-1.6.0-openjdk by calling the "appletviewer" application. This update also provides three defense in depth patches. (BZ#575745, BZ#575861, BZ#575789) 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.
