Opera is recommending users of its browser upgrade to the new Opera 9.64 for Windows to fix a number of security problems and improve functionality.
"Opera 9.64 is a recommended security and stability upgrade, incorporating the Opera Presto 2.1.1 user agent engine. Opera highly recommends all users to upgrade to Opera 9.64 to take advantage of these improvements," said the firm.
The browser fixes an issue where specially crafted JPEG images could be used to execute arbitrary code. It also addresses an issue where plug-ins could be used to attack users by allowing cross-domain scripting.
Other features in the updated browser allow it to more easily work with various Windows OS features. The updated version also works better when users are remotely connecting to enterprise networks protected by SSL security.
