What is CVE-2011-4531?

The Siemens Automation License Manager (ALM) versions 4.0 through 5.1+SP1+Upd1 are vulnerable to a denial of service attack. A remote attacker can exploit crafted content in the 'get_target_ocx_param' or 'send_target_ocx_param' commands, leading to a NULL pointer dereference and causing the daemon to crash. As a result, legitimate users may experience disruptions in service, highlighting the need for timely updates and robust security measures to mitigate this risk.
