Summary
FreeRDP: Integer overflow leading to heap buffer overflow in Orders Delta Points parsing
Details

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 sizeof(DELTAPOINT), allowing a malicious RDP peer to allocate an undersized heap buffer and then write beyond it during initialization. This issue is fixed in version 3.28.0.
