This covers it nicely. Upgrade to 7.16.1 and it looks like you are fully covered. They have removed the dodgy component and added the previously mentioned line to the config by default.![]()
Apache Log4j2 Remote Code Execution (RCE) Vulnerability - CVE-2021-44228 - ESA-2021-31
Subject: Apache Log4j2 Vulnerability - CVE-2021-44228, CVE-2021-45046, CVE-2021-45105, CVE-2021-44832 - ESA-2021-31 Note - We will update this announcement with new details as they emerge from our analysis. Please check back periodically. Update Log Dec 16, 2021 - 04:20 UTC - Update Summary...discuss.elastic.co
You need to add the elastic.co repository to your operating system. Then, every time you run a(or if Ubuntu,)Code:yum update
command to update the system, then it will poll the elastic servers and identify any needed or available updates.Code:apt update
The URL that I added is:which is polled when I request updates. It may be a different URL for CentOS, though.Code:https://artifacts.elastic.co/packages/7.x/apt stable InRelease
If there is an update available (perhaps once a month), then I do aand it downloads and installs the new update.Code:apt upgrade
Then I restart elasticsearch with thecommand, and it immediately updates the version in the XenForo control panel.Code:/etc/init.d/elasticsearch restart
If it is not updating or installing check that the repo is enabled.Apologies but how do I "add the elastic.co repository to your operating system"? I am running centos 7.x. When I run yum update now it tells me "Package(s) elasticsearch available, but not installed."
