Description

FreeRDP 3.0.0 before 3.32.2 built with WITH_AAD=ON contains a reachable assertion because its ARM gateway response parser accepts a missing or non-string redirectedServerCert field and passes a null buffer to the certificate parser. A malicious or malformed user-selected gateway can return such a response to abort the client process.
