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. cheers, joel
