Title:	Debian: Security Advisory (DLA-2870-1)
Summary:	The remote host is missing an update for the Debian 'apache-log4j2' package(s) announced via the DLA-2870-1 advisory.
Description:	Summary: The remote host is missing an update for the Debian 'apache-log4j2' package(s) announced via the DLA-2870-1 advisory. Vulnerability Insight: Apache Log4j2, a Java Logging Framework, is vulnerable to a remote code execution (RCE) attack where an attacker with permission to modify the logging configuration file can construct a malicious configuration using a JDBC Appender with a data source referencing a JNDI URI which can execute remote code. This issue is fixed by limiting JNDI data source names to the java protocol. For Debian 9 stretch, this problem has been fixed in version 2.12.4-0+deb9u1. We recommend that you upgrade your apache-log4j2 packages.
