| Doc Text: |
A flaw was found in FreeRDP. A remote attacker operating a malicious Remote Desktop (RD) Gateway can cause a denial of service (DoS) by sending a crafted Request to Send (RTS) packet with malformed authentication padding. When parsed, this invalid padding triggers an internal assertion failure that abruptly terminates the connecting client process. This flaw only affects FreeRDP clients built with the WITH_VERBOSE_WINPR_ASSERT flag enabled.
