The ajax_mediadiff function in DokuWiki before 2014-05-05a allows remote
attackers to access arbitrary images via a crafted namespace in the ns
parameter (CVE-2014-8762).

DokuWiki before 2014-05-05b, when using Active Directory for LDAP
authentication, allows remote attackers to bypass authentication via a
password starting with a null (\0) character and a valid user name, which
triggers an unauthenticated bind (CVE-2014-8763).

DokuWiki 2014-05-05a and earlier, when using Active Directory for LDAP
authentication, allows remote attackers to bypass authentication via a user
name and password starting with a null (\0) character, which triggers an
anonymous bind (CVE-2014-8764).");
