FreeRDP 3.0.0 before 3.32.0 does not remove card handles when Emulate SCardReleaseContext releases a smartcard-emulation context, so Emulate SCardTransmit later looks up the deleted parent context and reaches a terminating WINPR ASSERT. A malicious RDP server can crash a connecting client with smartcard emulation and redirection enabled by releasing a context, establishing another, and issuing SCardTransmit with the stale card handle.
Fix
