Type/Severity
Security Advisory: Important
Topic
An update for log4j 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.
Description
Log4j is a tool to help the programmer output log statements to a variety of output targets.
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.
