Description

A flaw was found in FreeRDP. A malicious peer, either a server or client, can exploit an out-of-bounds vulnerability during CredSSP/NLA authentication. By supplying a large 'extra count' (EC) value in a Kerberos GSS Wrap token, an attacker can cause the decryption operation to access memory outside of its intended buffer. This can lead to information disclosure, memory corruption, or a denial of service.
