Yes, it's on its way.  Expect it very soon.  I think the updated
packages have all (or almost all) completed building.

Sendmail developers published a patch to address this vulnerability.  If
you can't wait for the new packages, you can always download the source
for the current packages, apply the patch, and build new packages
yourself.  Note that there is no *known* exploit for this vulnerability,
though, and there have been no reports of compromises due to it.  I'm
sure somebody will correct me in short order if I'm sharing outdated
info here.
