Red Hat Security Advisory 2011-0857-01 - 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. 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. Various other issues were also addressed.
