Vulnerability from variot
Cisco Nexus 1000v Application Virtual Switch (AVS) devices before 5.2(1)SV3(1.5i) allow remote attackers to cause a denial of service (ESXi hypervisor crash and purple screen) via a crafted Cisco Discovery Protocol packet that triggers an out-of-bounds memory access, aka Bug ID CSCuw57985. The software replaces Vmware's built-in distributed virtual switch and includes two components: a virtual Ethernet module (VEM) running inside the hypervisor and an external virtual control engine module (VSM) that manages VEM. A security vulnerability exists in versions prior to Cisco Nexus 1000vAVS device 5.2(1)SV3 (1.5i). An attacker can leverage this issue to cause denial-of-service condition. This issue is being tracked by Cisco Bug ID CSCuw57985
