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 is a free implementation of the Remote Desktop Protocol (RDP), released under the Apache license. All FreeRDP clients prior to version 2.4.1 using gateway connections (/gt:rpc) fail to validate input data. A malicious gateway might allow client memory to be written out of bounds. This issue has been resolved in version 2.4.1. If you are unable to update then use /gt:http rather than /gt:rdp connections if possible or use a direct connection without a gateway.
