spice-vdagent up to and including 0.17.0 does not properly escape save directory before passing to shell, allowing local attacker with access to the session the agent runs in to inject arbitrary commands to be executed.
The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component.
