"A vulnerability in the Simple Network Management Protocol (SNMP) service of Cisco UCS 6300 Series Fabric Interconnects 
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.");
