Just a couple quick questions. Hope a couple wise owls might be able to answer ; )
I used to apply updates through the terminal without any care, since I don't use any ppa's or use any untrusted apps but lately I became interested in Ubuntu bugs, their fixes and most importantly the changes that would be made to my system. So, I found it easier to use the 'Update Manager' so I could use the link in the 'Changes' section to access the 'launchpad' page that discusses these issues.
Today when prompted for some specific updates, instead of being directed to a 'launchpad' page that I was accustomed to, I was directed to an unknown 'mitre.org' page.
I've searched the askubuntu site, as well as others, yet I've only found 1 thread that can come close to answering my questions. It was marked as [SOLVED], yet the OP's original question was never answered.
So to my questions...
What are CVE security updates and who issues them?
Why am I directed to an unknown website (to me anyways), that is funded by a government agency (look closely on the bottom of the 'Mitre' screenshot), when inquiring about the aforementioned updates?
