Advisory: Pages held in frames are able to change the location
of pages in unrelated frames on the parent page  haziran 11,
2008  Severity: Less Severe   Problem Description:   Pages from
different sources held on the same parent page should not be
able to modify the locations of each other. In affected Opera
versions, if a page contains frames from both a trusted but not
secured, and an untrusted source, the untrusted page is able to
replace the contents of a named trusted frame, causing it to
display misleading information.  Note that since the untrusted
frame could also display misleading information as its own
contents, authors of sites containing sensitive information
should not place frames from untrusted sources on their pages,
without offering the user some means to identify the content as
untrusted.   Opera's Response:
