------------------------------------------------------------------------- Debian LTS Advisory DLA-2870-1 debian-lts@lists.debian.org https://www.debian.org/lts/security/ Markus Koschany December 29, 2021 https://wiki.debian.org/LTS ------------------------------------------------------------------------- Package : apache-log4j2 Version : 2.12.4-0+deb9u1 CVE ID : CVE-2021-44832 Debian Bug : 1002813 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. For the detailed security status of apache-log4j2 please refer to its security tracker page at: https://security-tracker.debian.org/tracker/apache-log4j2 Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: https://wiki.debian.org/LTS
