  - 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)"
