 If, like many of us, you only have a single human user then you can
do a risk assessment and decide you don't need to update.  Nobody can
recommend running known-vulnerable software, but for _everything_ on
your LFS box you make your own choices.

 If you have multiple human users, it is generally a good idea to
mistrust them when you are in your sysadmin role.

 I'm not an expert either, and unlike regular distros we can't
subscribe somebody to the full-disclosure list where at least one
proof-of-concept has apparently circulated.
