freerdp: FreeRDP: Arbitrary code execution and denial of service via malicious server (important)
DOCUMENTATION: A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol. A malicious server can exploit a use-after-free vulnerability by enticing a client to connect to it. This can lead to a client-side crash, resulting in a Denial of Service (DoS), and potentially allow for arbitrary code execution due to heap corruption.
STATEMENT: For this vulnerability to be exploited, a client must connect to a maliciously-configured server. Red Hat recommends that FreeRDP clients are only used to connect to trusted servers.
