Ubuntu Security Notice 3396-1 - It was discovered that the JPEGImageReader class in OpenJDK would incorrectly read unused image data. An attacker could use this to specially construct a jpeg image file that when opened by a Java application would cause a denial of service. It was discovered that the JAR verifier in OpenJDK did not properly handle archives containing files missing digests. An attacker could use this to modify the signed contents of a JAR file. Various other issues were also addressed.
