pin well, following the 2009-01 security advisory (the one reporting the kernel leaks discovered through KLEAK), one was supposed to rebuild a kernel with up to date sources from the CVSWeb in order to get a secured system...or am I missing something? did they ever release fixed images?
On 8.1 is expected to get all security patches applied in the meantime since July 2018, which IIRC is when 8.0 went out XD
