CVE-2018-2677

First published: Sun Jan 14 2018(Updated: )

It was discovered that the implementation of the Path2D and CSS classes in the AWT component of OpenJDK did not limit the amount of memory allocated when creating object instance from a serialized form. A specially-crafted input could cause a Java application to use an excessive amount of memory when deserialized.
