Opera Window Object Suppressing Remote Denial of Service.

Opera Window Object Suppressing Remote Denial of Service.

Version Affected:
Opera 9.52

Release Date:
Disclosed: 28 September 2008
Release Date. 28 September ,2008

The opera browser is vulnerable to window object based denial of service attack. The opera fails to sanitize a check when window.close() function is called in number of dynamically generated events.. The function is called in a suppressed manner and kills the parent window directly by default which makes it vulnerable to denial of service attack.

This security issue is a result of design flaw in the browser.Scripts must not close windows that were not opened by script,if script specific code is designed. There must be a parent window confirmation check prior to close of window.
