Summary

Opera Web Browser 7.0 through 7.23 allows remote attackers to trick users into executing a malicious file by embedding a CLSID in the file name, which causes the malicious file to appear as a trusted file type, aka "File Download Extension Spoofing."

descriptionThe version of Opera installed on the remote host contains a flaw that may allow a malicious user to trick a user into running arbitrary code. The issue is triggered when an malicious website provides a file for download, but crafts the filename in such a way that the file is executed, rather than saved. It is possible that the flaw may allow arbitrary code execution resulting in a loss of confidentiality, integrity, and/or availability.
