TITLE:
Opera SSL Certificate "Stealing" Weakness

SECUNIA ADVISORY ID:
SA19480

VERIFY ADVISORY:
http://secunia.com/advisories/19480/

CRITICAL:
Not critical

IMPACT:
Spoofing

WHERE:
>From remote

SOFTWARE:
Opera 8.x
http://secunia.com/product/4932/

DESCRIPTION:
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.

The weakness has been confirmed in Opera 8.54. Prior versions may
also be affected.

SOLUTION:
Upgrade to version 9.0.

PROVIDED AND/OR DISCOVERED BY:
Jakob Balle, Secunia Research.
