Product information - security breach in log4j library

Le 21 décembre 2021 par Coralie

Government security agencies in many countries (FranceUKGermanyUSA) have reported on December 10, 2021 an important security vulnerability in a library very commonly used in all projects and software developed in Java. This vulnerability, identified in the Apache Log4j library used for logging, is likely to allow cyber attackers to take control of information systems.

This is a global security vulnerability and is rated as level 10 by the Apache Foundation.

As soon as this alert was issued and following investigations by its own cybersecurity teams, Dassault Systèmes implemented remediation actions and communicated to its customers through its knowledge base.
