impact of Important. A Common Vulnerability Scoring System (CVSS) base

Log4j is a tool to help the programmer output log statements to a
variety of output targets.

* It was found that when using remote logging with log4j socket server
the log4j server would deserialize any log event received via TCP or
UDP. An attacker could use this flaw to send a specially crafted log
event that, during deserialization, would execute arbitrary code in
the context of the logger application. (CVE-2017-5645)
