This Hotpatch package is not a replacement for updating to a log4j version that mitigates CVE-2021-44228 or CVE-2021-45046; it provides a temporary mitigation to CVE-2021-44228 by hotpatching the local Java virtual machines. To do so, it iterates through all running Java processes, performs several checks, and executes the Java virtual machine with the same permissions and capabilities as the running process to load the hotpatch. A local user could cause the hotpatch script to execute a binary with elevated privileges by running a custom java process that performs exec() of an SUID binary after the hotpatch has observed the process path and before it has observed its effective user ID."}, {"lang": "es", "value": "Las versiones del paquete hotpatch de Amazon AWS Apache Log4j anteriores a log4j-cve-2021-44228-hotpatch-1.3.5, est\u00e1n afectadas por una condici\u00f3n de carrera que podr\u00eda conllevar a una escalada de privilegios local.
