MIME-Version: 1.0 Synopsis: Important: java-1.6.0-openjdk security update Issue Date: 2011-06-08 CVE Numbers: CVE-2011-0865 CVE-2011-0862 CVE-2011-0867 CVE-2011-0869 CVE-2011-0868 CVE-2011-0864 CVE-2011-0871 These packages provide the OpenJDK 6 Java Runtime Environment and the OpenJDK 6 Software Development Kit. Integer overflow flaws were found in the way Java2D parsed JPEG images and user-supplied fonts. An attacker could use these flaws to execute arbitrary code with the privileges of the user running an untrusted applet or application. (CVE-2011-0862) It was found that the MediaTracker implementation created Component instances with unnecessary access privileges. A remote attacker could use this flaw to elevate their privileges by utilizing an untrusted applet or application that uses Swing. (CVE-2011-0871) A flaw was found in the HotSpot component in OpenJDK. Certain bytecode instructions confused the memory management within the Java Virtual Machine (JVM), resulting in an applet or application crashing. (CVE-2011-0864) An information leak flaw was found in the NetworkInterface class. An untrusted applet or application could use this flaw to access information about available network interfaces that should only be available to privileged code. (CVE-2011-0867) An incorrect float-to-long conversion, leading to an overflow, was found in the way certain objects (such as images and text) were transformed in Java2D. A remote attacker could use this flaw to crash an untrusted applet or application that uses Java2D. (CVE-2011-0868) It was found that untrusted applets and applications could misuse a SOAP connection to incorrectly set global HTTP proxy settings instead of setting them in a local scope.This flaw could be used to intercept HTTP requests. (CVE-2011-0869) A flaw was found in the way signed objects were deserialized. If trusted and untrusted code were running in the same Java Virtual Machine (JVM), and both were deserializing the same signed object, the untrusted code could modify said object by using this flaw to bypass the validation checks on signed objects. (CVE-2011-0865) Note: All of the above flaws can only be remotely triggered in OpenJDK by calling the "appletviewer" application. All users of java-1.6.0-openjdk are advised to upgrade to these updated packages, which provide OpenJDK 6 b20 / IcedTea 1.9.8 and resolve these issues. All running instances of OpenJDK Java must be restarted for the update to take effect.
