We were told that these all required elevated privileges to hit, and so
were not classified as individual vulnerabilities. If the Apparmor
maintainer tells us that these really all should be assigned a CVE, we
will be glad to do so, but until then, we're just going to stick with
the ones that we have assigned already.
thanks,
