NVD Description

Note: Versions mentioned in the description apply only to the upstream libwinpr package and not the libwinpr package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

FreeRDP before 3.32.2 fails to cap the OutputBufferLength in serial device-control IRP requests, allowing malicious servers to trigger excessive memory allocation. Attackers running a server with serial redirection can send an IRP_MJ_DEVICE_CONTROL request with IOCTL_USBPRINT_GET_1284_ID and a near-maximum length to exhaust client memory.
