It was discovered that the DCG (Distributed Garbage Collector) implementation in the RMI component of OpenJDK failed to correctly handle references. A remote attacker could possibly use this flaw to execute arbitrary code with the privileges of RMI registry or a Java RMI application.

It was discovered that the JAR (Java ARchive) verifier in the Security component of OpenJDK did not correctly handle files inside archives with missing digest. An attacker could possibly use this flaw to manipulate content of a singed JAR, bypassing intended verification.

It was discovered that the JPEGImageReader implementation in the 2D component of OpenJDK would, in certain cases, read all image data even if that was not used later. A specially crafted image could cause a Java application to temporarily use an excessive amount of CPU and memory.

Eclipse Jetty could allow a remote attacker to obtain sensitive information, caused by a flaw when configured for showing a listing of directory contents. By sending a specially-crafted request, a remote attacker could exploit this vulnerability to obtain sensitive information.
