On the heels of the latest Opera beta debuting last week, the stable version of Opera has been updated to incorporate several security fixes.
Available for Windows and Mac, Opera 10.54 includes five security-related repairs, but the company has only fully disclosed the nature of one of them. In addition to the security repairs, the Mac version received multiple non-security bug fixes.
The one security fix that Opera disclosed information about concerns a hole it had rated as extremely severe. The bug was actually on Windows systems that allowed font handling to be used as an exploit vector. Microsoft issued a patch for the hole, but for users who haven't patched it yet, Opera has released their own fix that prevents the browser from being used to exploit it. For the other four fixes, only their severity was released.
