[原文]Opera 7.50 and earlier allows remote web sites to provide a "Shortcut Icon" (favicon) that is wider than expected, which could allow the web sites to spoof a trusted domain and facilitate phishing attacks using a wide icon and extra spaces.
Opera Web Browser contains a flaw that may allow a malicious user to spoof a trusted web site. The issue is triggered when a favicon.ico image is crafted to resemble the text of a trusted web site address. It is possible that the flaw may allow impersonation of a trusted web site resulting in a loss of integrity.
Upgrade to version 7.51 or higher, as it has been reported to fix this vulnerability. An upgrade is required as there are no known workarounds.
