CVE-2020-25650 [MEDIUM] CVE-2020-25650 spice-vdagent: memory DoS via arbitrary entries in active_xfers hash table
CVE-2020-25650 spice-vdagent: memory DoS via arbitrary entries in active_xfers hash table
The following flaw was reported by SUSE Security:
The `spice-vdagentd` maintains a hash map named `active_xfers` that maps `task_ids` to UNIX domain socket connections they belong to. These `task_ids`
refer to ongoing file transfers from the host to the virtual machine. An arbitrary client connected to `spice-vdagentd` via a UNIX domain socket can trigger an entry into this hash map, without the requirement that the client is associated with the currently active graphical session (function `do_agent_file_xfer_status`, specifically `vdagentd.c:1025`). There is no limit on the maximum amount of file transfers ongoing in parallel and there are no timeouts applied for a file transfer to be finished.
