FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, a missing bounds check in `sma

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, a missing bounds check in smartcard_unpack_read_size_align() (libfreerdp/utils/smartcard_pack.c:1703) allows a malicious RDP server to crash the FreeRDP client via a reachable WINPR_ASSERT - abort(). The crash occurs in upstream builds where WITH_VERBOSE_WINPR_ASSERT=ON (default in FreeRDP 3.22.0 / current WinPR CMake defaults). Smartcard redirection must be explicitly enabled by the user (e.g., xfreerdp /smartcard.

/smartcard-logon implies /smartcard). Version 3.23.0 fixes the issue.
