Ubuntu Security Notice 4083-1 - It was discovered that OpenJDK did not sufficiently validate serial streams before deserializing suppressed exceptions in some situations. An attacker could use this to specially craft an object that, when deserialized, would cause a denial of service. It was discovered that in some situations OpenJDK did not properly bound the amount of memory allocated during object deserialization. An attacker could use this to specially craft an object that, when deserialized, would cause a denial of service. Various other issues were also addressed.
