Opera has made available the fix for the desktop version Opera 7.54 for all OSes in response to the following security advisories, some of which are by Secunia research:
Named frames or windows can be hi-jacked by malicious frames or windows.
Periods in the file name and non-breaking spaces in the Content-Type header can make the save/open dialog misleading. A user may be convinced that an executable file is something else, for example a PDF document.
Applets have access to sun.* packages
Liveconnect: com.opera.EcmascriptObject constructor is accessible to Java
Liveconnect reveals the path to the user's home directory. This can make other vulnerabilities easier to exploit.
Severity: Moderate/High
Opera has tightened origin check for frames and in addition to those fixes, improved support for the "must-revalidate" cache directive.
