FreeRDP before 3.32.2 Use-After-Free via dyn-channel-dump Module

Summary

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.

Remediation

1. Inventory every FreeRDP FreeRDP deployment, including staging.
2. Upgrade FreeRDP FreeRDP to 3.32.2.
3. Confirm the running version after the upgrade.
