TITLE

Apache Log4j Input validation error vulnerability

DESCRIPTION

Apache Log4j2 versions 2.0-beta7 through 2.17.0 (excluding security fix releases 2.3.2 and 2.12.4) are vulnerable to a remote code execution (RCE) attack when a configuration uses a JDBC Appender with a JNDI LDAP data source URI when an attacker has control of the target LDAP server. This issue is fixed by limiting JNDI data source names to the java protocol in Log4j2 versions 2.17.1, 2.12.4, and 2.3.2. Apache Log4j is a Java-based open source logging tool of the Apache Foundation. Apache Log4j2 2.0-beta7 to 2.17.0 versions have a security vulnerability, which stems from the lack of effective protection and filtering for JDBC Appender and JNDI in the software. The purpose of this text-only errata is to inform you about the security issues fixed in this release.
