Security Fix(es):

  * 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)");
