"A vulnerability in the Simple Network Management Protocol (SNMP) service of Cisco FXOS Software for Firepower 4100 
Series and Firepower 9300 Security Appliances could allow an authenticated, remote attacker to cause a denial of 
service (DoS) condition on an affected device. This vulnerability is due to the improper handling of specific SNMP 
requests. An attacker could exploit this vulnerability by sending a crafted SNMP request to an affected device. 
A successful exploit could allow the attacker to cause the affected device to reload, resulting in a DoS condition. 
Note: This vulnerability affects all supported SNMP versions. To exploit this vulnerability through SNMPv2c or earlier, 
an attacker must know the SNMP community string that is configured on an affected device. To exploit this vulnerability 
through SNMPv3, the attacker must have valid credentials for an SNMP user who is configured on the affected device.

Please see the included Cisco BIDs and Cisco Security Advisory for more information.");
