AMD Response to Log4j (Log4Shell) Vulnerability


### Summary 1/17/2022 Update: AMD has completed our investigation of the Apache Log4j vulnerability. AMD believes no AMD products are affected. 12/15/2021: AMD is actively investigating potential impacts of the Apache Log4j vulnerability (Log4Shell) to AMD products. The description of the vulnerability, published by the national vulnerability database (NVD) states: CVE-2021-44228 Apache Log4j2 <=2.14.1 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. In previous releases (>2.10) this behavior can be mitigated by setting system property "log4j2.formatMsgNoLookups" to “true” or it can be mitigated in prior releases (<2.10) by removing the JndiLookup class from the classpath (example: zip -q -d log4j-core-*.jar org/apache/logging/log4j/core/lookup/JndiLookup.class). ### Affected Products Currently, no AMD products have been identified as affected. ### References 1. <https://logging.apache.org/log4j/2.x/security.html> 2. <https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-44228> 3. <https://nvd.nist.gov/vuln/detail/CVE-2021-44228> DISCLAIMER The information contained herein is for informational purposes only and is subject to change without notice.
