The remote device is missing a vendor-supplied security patch.
According to its self-reported version, the version of Cisco IOS XE
running on the remote host is affected by a denial of service
vulnerability in the Session Initiation Protocol (SIP) implementation.
An unauthenticated, remote attacker could potentially exploit this
issue to cause a denial of service.
Note that this issue only affects hosts configured to process SIP
messages. SIP is not enabled by default on newer IOS XE versions.
