CVE-2012-5624: Infoleak
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).

Other sources
The XMLHttpRequest object in Qt before 4.8.4 enables http redirection to the file scheme, which allows man-in-the-middle attackers to force the read of arbitrary local files and possibly obtain sensitive information via a file: URL to a QML application.
