CVE Request -- Qt (x < 4.8.4): QML XmlHttpRequest insecure redirection

[Jan Lieskovsky <jlieskov () redhat com>]

Hello Kurt, Steve, vendors,

  Qt upstream has released 4.8.4 version correcting one security
issue:

An information disclosure flaw was found in the way XMLHttpRequest
object implementation in Qt, a software toolkit for developing
applications, performed management of certain HTTP responses.
Previous implementation allowed redirection from HTTP protocol
to file schemas. Also the redirection handling was performed
automatically by QML application and could not be disabled.
A remote attacker could use this flaw to cause QML application
in an unauthorized way to read local file content by causing
the HTTP response for the application to be a redirect to
a file: URL (file scheme).

Thank you && Regards, Jan.
