[GLSA-200408-05] Opera: Multiple new vulnerabilities

Vulnerability Assessment Summary
Opera: Multiple new vulnerabilities

Detailed Explanation for this Vulnerability Assessment
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, a possible hacker 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.
