Comment (by sambthompson):

 Replying to [comment:9 tobypeterson]:
 > that isn't ideal considering that c-ares does have the occasional CVE.
 (Most recent one was just this February.)
 Agreed. Upstream haven't (yet) rejected the report but are engaging with
 it (and the other issue affecting even earlier OS versions), so would hope
 to still get a fixed 1.30.1.
