An update for log4j is now available for openEuler-20.03-LTS-SP1 and openEuler-20.03-LTS-SP2 Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2021-1462 Final 1.0 1.0 2021-12-11 Initial 2021-12-11 2021-12-11 openEuler SA Tool V1.0 2021-12-11 log4j security update An update for log4j is now available for openEuler-20.03-LTS-SP1 and openEuler-20.03-LTS-SP2. Java logging package. Security Fix(es): The details of a high-risk vulnerability in Apache Log4j2 have been disclosed. Attackers can use the vulnerability to execute code remotely. Some reports carry suspected POC; Apache Log4j2 is a Java-based logging tool. This tool rewrites the Log4j framework and introduces a large number of rich features. The log framework is widely used in business system development to record log information. In most cases, developers may write error messages caused by user input into the log. The trigger condition of this vulnerability is that as long as the data input by external users will be recorded in the log, it can cause remote code execution.(CVE-2021-44228) An update for log4j is now available for openEuler-20.03-LTS-SP1 and openEuler-20.03-LTS-SP2. openEuler Security has rated this update as having a security impact of critical. A Common Vunlnerability Scoring System(CVSS)base score,which gives a detailed severity rating, is available for each vulnerability from the CVElink(s) in the References section.
