"From Red Hat Security Advisory 2018:0592 :

An update for slf4j is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security
impact of Important. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

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.

Red Hat would like to thank Chris McCown for reporting this issue."
