TITLE

Debian Security Advisory 5020-1

DESCRIPTION

Apache Log4j2 2.0-beta9 through 2.15.0 (excluding security releases 2.12.2, 2.12.3, and 2.3.1) 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 (along with 2.12.2, 2.12.3, and 2.3.1), 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. Apache log4j2 has a denial of service vulnerability. This update also fixes CVE-2020-9488 in the oldstable distribution (buster). Improper validation of certificate with host mismatch in Apache Log4j SMTP appender. This could allow an SMTPS connection to be intercepted by a man-in-the-middle attack which could leak any log messages sent through that appender. For the oldstable distribution (buster), this problem has been fixed in version 2.15.0-1~deb10u1. For the stable distribution (bullseye), this problem has been fixed in version 2.15.0-1~deb11u1. We recommend that you upgrade your apache-log4j2 packages.
