Description

A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol. A double-free vulnerability exists when a FreeRDP client processes a specially crafted `.rdp` connection file. An attacker could convince a victim to open a malicious `.rdp` file, leading to a size-controlled double-free. This could potentially allow for arbitrary code execution on the affected system.
