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. A flaw was found in the way the XMLSchemaValidator class in the JAXP component of OpenJDK enforced the "use-grammar-pool-only" feature. A specially-crafted XML file could possibly use this flaw to manipulate with the validation process in certain cases.

Remediation
