You may have heard in the media about the recent security vulnerability identified in the Linux Kernel, called Dirty COW (Dirty copy-on-write).

Dirty COW (CVE-2016-5195) is a privilege escalation vulnerability in the Linux Kernel. You can read more at https://en.wikipedia.org/wiki/Dirty_COW

This security vulnerability is called a “Zero Day Exploit” because the day it was disclosed publicly, active exploits of the issue had already been discovered, attacking Linux servers on the Internet. Any Linux based system with Ports exposed on the Internet could be attacked using this exploit. That’s particularly nasty.

Did you know Android phones are also based on the Linux Kernel? And potentially susceptible to this issue too? Fun times.

Agileware have deployed the security patch which addresses this issue to all servers we manage. Servers were rebooted as per the requirement for Kernel updates.
