CVE-2012-4381

MediaWiki before 1.18.5, and 1.19.x before 1.19.2 saves passwords in the
local database, (1) which could make it easier for context-dependent
attackers to obtain cleartext passwords via a brute-force attack or, (2)
when an authentication plugin returns a false in the strict function, could
allow remote attackers to use old passwords for non-existing accounts in an
external authentication system via unspecified vectors.
