Description:
Secunia Research has discovered a vulnerability in Opera, which can be exploited by malicious people to trick users into executing malicious files.
The vulnerability is caused due to the filename and the "Content-Type" header not being sufficiently validated before being displayed in the file download dialog. This can be exploited to spoof file types in the download dialog by passing specially crafted "Content-Disposition" and "Content-Type" headers containing dots and ASCII character code 160.
Successful exploitation may result in users being tricked into executing a malicious file via the download dialog.
The vulnerability has been confirmed on Opera 7.54 for Windows. Other versions may also be affected.
Solution:
Update to version 7.54u1.
