Summary

  o A vulnerability in Cisco AMP for Endpoints Mac Connector Software installed
    on Apple macOS 10.12 could allow an unauthenticated, remote attacker to
    cause a kernel panic on an affected system, resulting in a denial of
    service (DoS) condition.

    The vulnerability exists if the affected software is running in Block
    network conviction mode. Exploitation could occur if the system that is
    running the affected software starts a server process and an address in the
    IP blacklist cache of the affected software attempts to connect to the
    affected system. A successful exploit could allow the attacker to cause a
    kernel panic on the system that is running the affected software, resulting
    in a DoS condition.

    There are no workarounds that address this vulnerability.
