I do not know if wheezy is/can be affected, however the fix promulgated by the link to the UCR announcement is wrong, at least for my wheezy install, in that when I investigated my machine, the dots in that string: net.ipv4.tcp_challenge_ack_limit = 999999999 to add should be changed to forward slashes: net/ipv4/tcp_challenge_ack_limit = 999999999 as that is the directory structure on this wheezy based machine, and then the following update command: sysctl -p works w/o error. All done as root of course. No clue if the fix works, I haven't been attacked that I am aware of.
