======================================================================
1) Affected Software
Opera 8.54
Prior versions may also be affected.
======================================================================
2) Severity
Rating: Not critical
Impact: Spoofing
Where: From remote
======================================================================
3) Description of Vulnerabilities
Secunia Research has discovered a weakness in Opera, which can be
exploited to display the SSL certificate from a trusted site on an
untrusted site.
The weakness is caused due to Opera not resetting the SSL security
bar after displaying a download dialog from a SSL enabled web site.
This allows an untrusted web site to display yellow SSL security bar
from a trusted web site.
NOTE: A more convincing exploit can be done using pop-up windows,
which do not have a visible address bar.
======================================================================
4) Solution
Upgrade to version 9.0.
======================================================================
