Run ls -lo /var/db/pkg/vuln.xml to view permissions.

You can use something like this to check all files with specified flag

find /path/to/jail/ -flags +schg -exec ls -lo {} +

Then check what is your kern_securelevel settings in host and in a jails 
rc.conf. You cannot modify files witch flags is securelevel is higher 
than 0.
