GLSA-200408-05 : Opera: Multiple new vulnerabilities

This script is Copyright (C) 2004-2014 Tenable Network Security, Inc.


Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-200408-05
(Opera: Multiple new vulnerabilities)

Multiple vulnerabilities have been found in the Opera web browser.
Opera fails to deny write access to the 'location' browser object. An
attacker can overwrite methods in this object and gain script access to
any page that uses one of these methods. Furthermore, access to file://
URLs is possible even from pages loaded using other protocols. Finally,
spoofing a legitimate web page is still possible, despite the fixes
announced in GLSA 200407-15.

Impact :

By enticing an user to visit specially crafted web pages, an attacker
can read files located on the victim's file system, read emails written
or received by M2, Opera's mail program, steal cookies, spoof URLs,
track user browsing history, etc.

Workaround :

There is no known workaround at this time. All users are encouraged to
upgrade to the latest available version.
