CVE-2020-25652 [MEDIUM] CVE-2020-25652 spice-vdagent: possibility to exhaust file descriptors in vdagentd
CVE-2020-25652 spice-vdagent: possibility to exhaust file descriptors in vdagentd
The following flaw was reported by SUSE Security:
`spice-vdagentd` does not apply a limit to the amount of client connections that can be established via the UNIX domain socket in `/run/spice-vdagentd/spice-vdagent-sock`. Also existing connections aren't subject to a timeout or any kind of preconditions for them to stay alive. Any local user in the VM can prevent legitimate `spice-vdagent` instances from connecting to the `spice-vdagentd` daemon. `spice-vdagentd` will become unable to open further connections for legitimate clients or perform other tasks.
