Overview

openjdk-jre is a free and open-source implementation of the Java Platform, Standard Edition (Java SE).

Affected versions of this package are vulnerable to Improper Input Validation. It was discovered that the StringBuffer and StringBuilder classes implementation in the Libraries component failed to properly validate the value of the count attribute during object deserialization. A specially-crafted input could cause a Java application to misbehave because of StringBuffer or StringBuilder object instances in an inconsistent state.
