A flaw was found in the way the spice-vdagentd daemon handled file
transfers from the host system to the virtual machine. Any unprivileged
local guest user with access to the UNIX domain socket path
/run/spice-vdagentd/spice-vdagent-sock could use this flaw to perform a
memory denial of service for spice-vdagentd or even other processes in the
VM system. The highest threat from this vulnerability is to system
availability. This flaw affects spice-vdagent versions 0.20 and previous
versions.
