Summary

The Simple Logging Facade for Java or (SLF4J) is a simple facade for various logging APIs allowing the end-user to plug in the desired implementation at deployment time. SLF4J also allows for a gradual migration path away from Jakarta Commons Logging (JCL).
Security Fix(es):
* slf4j: Deserialisation vulnerability in EventData constructor can allow for arbitrary code execution (CVE-2018-8088)
For more details about the security issue(s), including the impact, a CVSS score, and other related information, refer to the CVE page(s) listed in the References section.
