History
Ben Noordhuis b7466e31e4 idna: fix OOB read in punycode decoder 
libuv was vulnerable to out-of-bounds reads in the uv__idna_toascii()
function which is used to convert strings to ASCII. This is called by
the DNS resolution function and can lead to information disclosures or
crashes.

Reported by Eric Sesterhenn in collaboration with Cure53 and ExpressVPN.
