The vulnerability is caused due to a format string error when handling SSL certificates and can be exploited via a specially crafted SSL certificate containing format specifiers in the "CN" field. Successful exploitation may allow execution of arbitrary code when e.g. visiting a malicious website, but requires that the application is running with either the "-dump" or "-backend" option. The vulnerability is reported in version 0.5.1. Other versions may also be affected. SOLUTION: Only visit trusted sites when running with the "-backend" or "-dump" options. PROVIDED AND/OR DISCOVERED BY: Reported by an anonymous person.
