Revision 070fae6d0ff49e63bfd5f2bdc66f8eb1df3b6557 authored by Christian Heimes on 02 July 2019, 18:39:42 UTC, committed by Ned Deily on 02 July 2019, 18:42:08 UTC 
bpo-37463: match_hostname requires quad-dotted IPv4 (GH-14499)
 


ssl.match_hostname() no longer accepts IPv4 addresses with additional text
after the address and only quad-dotted notation without trailing
whitespaces. Some inet_aton() implementations ignore whitespace and all data
after whitespace, e.g. '127.0.0.1 whatever'.

Short notations like '127.1' for '127.0.0.1' were already filtered out.

The bug was initially found by Dominik Czarnota and reported by Paul Kehrer.
