CVE-2017-6656
A vulnerability in Session Initiation Protocol (SIP) call handling of Cisco IP Phone 8800 Series devices could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition due to the SIP process unexpectedly restarting.
Does this matter?
Lower severity and a low EPSS score (1.66%). Track it; it rarely justifies an emergency change on its own.
