CVE-2026-57156 FreeRDP: Integer overflow leading to heap buffer overflow in Orders Delta Points parsing

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.28.0 on 32-bit builds, FreeRDP clients contain an integer overflow in updatereaddeltapoints in libfreerdp/core/orders.c when multiplying an attacker-controlled point count by sizeofDELTAPOINT, allowing a malicious RDP pee...
