An update for flink is now available for openEuler-20.03-LTS-SP1 Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2022-1943 Final 1.0 1.0 2022-09-23 Initial 2022-09-23 2022-09-23 openEuler SA Tool V1.0 2022-09-23 flink security update An update for flink is now available for openEuler-20.03-LTS-SP1. Apache Flink is a framework and distributed processing engine for stateful computations over unbounded and bounded data streams. Flink has been designed to run in all common cluster environments, perform computations at in-memory speed and at any scale. Security Fix(es): Apache Log4j2 2.0-beta9 through 2.12.1 and 2.13.0 through 2.15.0 JNDI features used in configuration, log messages, and parameters do not protect against attacker controlled LDAP and other JNDI related endpoints. An attacker who can control log messages or log message parameters can execute arbitrary code loaded from LDAP servers when message lookup substitution is enabled. From log4j 2.15.0, this behavior has been disabled by default. From version 2.16.0, this functionality has been completely removed. Note that this vulnerability is specific to log4j-core and does not affect log4net, log4cxx, or other Apache Logging Services projects.(CVE-2021-44228) An update for flink is now available for openEuler-20.03-LTS-SP1. openEuler Security has rated this update as having a security impact of critical.
