Debian stable is affected.

If you're relying on HTTP or FTP - you're screwed. If you prefer HTTPS
and SSH - it does not concern you.

To workaround the problem, use (/etc/sysctl.conf is preferred):

sysctl -w net.ipv4.tcp_challenge_ack_limit=999999999

To solve the problem you should wait until Debian-provided kernels gain
a backport for CVE-2016-5696.
