12.50. It is, therefore, affected by a local code execution
vulnerability due to an overflow condition that is triggered when
handling scenario files (.lrs). A local attacker can exploit this, via
a specially crafted scenario file, to cause a stack-based buffer
overflow, resulting in the execution of arbitrary code.");
