## Description

The DecodeHSTSPreloadRaw function in net/http/transport\_security\_state.cc
in Google Chrome before 43.0.2357.130 does not properly canonicalize DNS
hostnames before making comparisons to HSTS or HPKP preload entries, which
allows remote attackers to bypass intended access restrictions via a string
that (1) ends in a . (dot) character or (2) is not entirely lowercase.
