A flaw was found in the SPICE file transfer protocol. File data from the host system can end up in full or in parts in the client connection of an illegitimate local user in the VM system. Active file transfers from other users could also be interrupted, resulting in a denial of service. The highest threat from this vulnerability is to data confidentiality as well as system availability. This flaw affects spice-vdagent versions 0.20 and prior.

CVE-2020-25651 spice-vdagent: possible file transfer DoS and information leak via active_xfers hash map
A flaw was found in the SPICE file transfer protocol. It was reported by SUSE Security as follows:
The host application (tested with `remote-viewer` from the virt-viewer package) chooses an incrementally growing `task_id` for file exchanges
which starts counting at 1. Thus the `task_id` is predictable. Since any unauthenticated local client can replace the mapping of `task_id` to client
connection by its own client connection, there is a possibility for an attacker to obtain parts of the transferred file data.
File data from the host system can end up in full or in parts in the client connection of an illegitimate local user in the VM system. Exploitability will be difficult if there
