DESCRIPTION:
SEC Consult has reported a vulnerability in SecSigner, which can be
exploited by malicious people to compromise a user's system.

The vulnerability is caused due to the applet insecurely handling the
"seccommerce.resource" property defined in secsigner.properties (when
the "seccommerce.resource.localcopy" property is set to "on"), which
leads to insufficient authenticity validation of downloaded resource
files. This can be exploited to download and execute arbitrary files
by tricking a user into visiting a malicious web site.

The vulnerability is reported in versions 3.5.0 prior to 2011-11-12.

SOLUTION:
The vendor has released an updated version 3.5.0 on 2011-11-14.
Additionally enable the certificate revocation check via e.g. OCSP or
Java preferences.
