Description

Opera contains a flaw that may allow a remote user to spoof file types and cause a target user to execute arbitrary code. The issue is triggered when an additional '.' is appended to the end of a filename, which could allow an extension to be spoofed. It is possible that the flaw may allow a script insertion attack, if the user chooses to view an attachment resulting in a loss of confidentiality.
