The phrase "Upgrade your vulnerable system" implies performing the full
upgrade as per handbook, which means kernel and world.
I would never recommend rebuilding world without kernel, even it appears
to be without risk, for three extremely good reasons:
o the handbook says not to, and explains why
o so that you will never fall into the habit of just building world
and get caught out one day when it bites you
o so that the correct version of your system will be reflected in
the output of 'uname -a' eg: 5.3-RELEASE-p32 and hence you will
be able to track the patchlevel of your system
That said, I wouldn't discourage you from patching sendmail immediately
to correct the vulnerability as per procedure 2) if time is critical but
I would certainly encourage following through with a system update as per
1) as soon as possible.
