The Good part is that this will be patched very soon if it has not been already. The Bad part is that these things happen to such a great OS like Linux with such potential. If you are running a desktop/workstation you should not be making any remote services available anyway (be sure and check if you are). If you are running a server or are considering it go with OpenBSD, they just released 3.0, and OpenBSD has not had a remote exploit for going on 4 years with the default install.
