Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

FreeRDP before 3.32.2 contains a cross-thread use-after-free vulnerability in the freerdp-proxy dyn-channel-dump module during session teardown. A malicious RDP target can send dynamic channel data while the front client disconnects, letting the client thread read freed ChannelData and crash the proxy process.
