So there is this vulnerability announced earlier this week for Linux machines. It affects GLIBC 2.9 and higher.
Pretty nasty one if it were ever weaponized. I remember a time when you had to open an attachment to get infected. Then got sophisticated and required just reading an email. Now sending an email will not get the client infected but the server.
So instead of working out, I am patching machines. So, I get a pass.
