Well I didn't want to reproduce the entire thread. The basic summary is Linus feels that labeling bugs as a security threat should not be pointed out as such, rather keep such information private, even though the fix is public.
Because life is short. If you want security patches, find a vendor to help filter the bad bugs from the big bugs for you.
In the meantime, hackers see the fix, recognize the security risk, and build exploits long before your vendors even recognize it as a potential security risk (probably only after it is exploited in the wild would they understand it as such). Good luck with that.
