Google Chrome before 41.0.2272.76, when Instant Extended mode is used, does not properly consider the interaction between the "1993 search" features and restore-from-disk RELOAD transitions, which makes it easier for remote attackers to spoof the address bar for a search-results page by leveraging (1) a compromised search engine or (2) an XSS vulnerability in a search engine, a different vulnerability than CVE-2015-1231..
