DESCRIPTION:
A security issue has been reported in S-Banking and S-Finanzstatus,
which can be exploited by malicious people to conduct spoofing
attacks.

The security issue is caused due to the application not properly
verifying the server certificate of the bank's server. This can be
exploited to e.g. spoof the server via a MitM (Man-in-the-Middle)
attack and e.g. disclose potentially sensitive information.

The vulnerability is reported in versions prior to 1.6.3 for the
iPhone / iPod touch and prior to 1.5.3 for the iPad.

SOLUTION:
Update to version 1.6.3 for the iPhone or 1.5.3 for the iPad.
