Magento 2 – Dirty COW Linux OS Vulnerability

In Magento 2, you will see notification about Dirty COW Linux OS Vulnerability. So what is this ? What it means ?

Dirty COW (CVE-2016-5195) is a privilege escalation vulnerability in the Linux Kernel that can allow a local user (like a web hosting account) to gain root access to the server. This can also be a huge problem if your Magento store is compromised and the attacker has the ability to upload files to your server or hosting account.

If you manage your own server, you will need to update the kernel (and reboot your server) once the security patch is issued by your operating system providers.

If you do not manage your own server or if you are using shared hosting, contact your server administrator or hosting provider to make sure that you are protected against this vulnerability.

Please take news into consideration and secure your online store.
