Ubuntu Security Notice 1755-1 - It was discovered that OpenJDK did not properly validate certain types of images. A remote attacker could exploit this to cause OpenJDK to crash. It was discovered that OpenJDK did not properly check return values when performing color conversion for images. If a user were tricked into opening a crafted image with OpenJDK, such as with the Java plugin, a remote attacker could cause OpenJDK to crash or execute arbitrary code outside of the Java sandbox with the privileges of the user invoking the program. Various other issues were also addressed.
