+---------------------------------------------------------------------
Summary
=======
A vulnerability in the Simple Network Management Protocol (SNMP) input packet
processor of Cisco NX-OS Software could allow an authenticated, remote
attacker to cause the SNMP application on an affected device to restart
unexpectedly.
The vulnerability is due to improper validation of SNMP protocol data units
(PDUs) in SNMP packets. An attacker could exploit this vulnerability by
sending a crafted SNMP packet to an affected device. A successful exploit
could allow the attacker to cause the SNMP application to restart multiple
times, leading to a system-level restart and a denial of service (DoS)
condition.
Cisco has released software updates that address this vulnerability. There are
no workarounds that address this vulnerability.

Cisco Security Advisory: Cisco NX-OS Software Border Gateway Protocol Denial
of Service Vulnerability
Advisory ID: cisco-sa-20180620-nxosbgp
Revision: 1.0
For Public Release: 2018 June 20 16:00 GMT
Last Updated: 2018 June 20 16:00 GMT
CVE ID(s): CVE-2018-0295
CVSS Score v(3): 8.6 CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H
+---------------------------------------------------------------------
Summary
=======
A vulnerability in the Border Gateway Protocol (BGP) implementation of Cisco
NX-OS Software could allow an unauthenticated, remote attacker to cause a
denial of service (DoS) condition due to the device unexpectedly reloading.
The vulnerability is due to incomplete input validation of the BGP update
messages. An attacker could exploit this vulnerability by sending a crafted
BGP update message to the targeted device. An exploit could allow the attacker
to cause the switch to reload unexpectedly.
The Cisco implementation of the BGP protocol only accepts incoming BGP traffic
from explicitly defined peers. To exploit this vulnerability, an attacker must
be able to send the malicious packets over a TCP connection that appears to
come from a trusted BGP peer or inject malformed messages into the victim's
BGP network. This would require obtaining information about the BGP peers in
the affected system's trusted network.
The vulnerability may be triggered when the router receives a malformed BGP
message from a peer on an existing BGP session. At least one BGP neighbor
session must be established for a router to be vulnerable.
Cisco has released software updates that address this vulnerability. There are
no workarounds that address this vulnerability.
