An attacker could exploit this vulnerability by sending DHCP request packets to an affected device. A successful exploit could allow the attacker to cause packets to wedge in the queue, creating a DoS condition for downstream devices of the affected system and requiring that the system restart to drain the queue.\r\n\r Note: This vulnerability can be exploited with either unicast or broadcast DHCP packets on a VLAN that does not have DHCP snooping enabled.", "affected": [ { "vendor": "Cisco", "product": "Cisco IOS XE Software", "versions": [ { "version": "16.11.1", "status": "affected" }, { "version": "16.11.1a", "status": "affected" }, { "version": "16.11.2", "status": "affected" }, { "version": "16.11.1s", "status": "affected" }, { "version": "16.12.1", "status": "affected" }, { "version": "16.12.1s", "status": "affected" }, { "version": "16.12.1a", "status": "affected" }, { "version": "16.12.1c", "status": "affected" }, { "version": "16.12.2", "status": "affected" }, { "version": "16.12.3", "status": "affected" }, { "version": "16.12.8", "status": "affected" }, { "version": "16.12.2s", "status": "affected" }, { "version": "16.12.4", "status": "affected" }, { "version": "16.12.3s", "status": "affected" }, { "version": "16.12.5", "status": "affected" }, { "version": "16.12.6", "status": "affected" }, { "version": "16.12.7", "status": "affected" }, { "version": "17.1.1", "status": "affected" }, { "version": "17.1.1s", "status": "affected" }, { "version": "17.1.1t", "status": "affected" }, { "version": "17.1.3", "status": "affected" }, { "version": "17.2.1", "status": "affected" }, { "version": "17.2.1r", "status": "affected" }, { "version": "17.2.1v", "status": "affected" }, { "version": "17.2.2", "status": "affected" }, { "version": "17.2.3", "status": "affected" }, { "version": "17.3.1", "status": "affected" }, { "version": "17.3.2", "status": "affected" }, { "version": "17.3.3", "status": "affected" }, { "version": "17.3.1a", "status": "affected" }, { "version": "17.3.4", "status": "affected" }, { "version": "17.3.5", "status": "affected" }, { "version": "17.3.4a", "status": "affected" }, { "version": "17.3.6", "status": "affected" }, { "version": "17.3.7", "status": "affected" }, { "version": "17.3.8", "status": "affected" }, { "version": "17.3.8a", "status": "affected" }, { "version": "17.4.1", "status": "affected" }, { "version": "17.4.2", "status": "affected" }, { "version": "17.4.1a", "status": "affected" }, { "version": "17.4.1b", "status": "affected" }, { "version": "17.5.1", "status": "affected" }, { "version": "17.5.1a", "status": "affected" }, { "version": "17.6.1", "status": "affected" }, { "version": "17.6.2", "status": "affected" }, { "version": "17.6.1a", "status": "affected" }, { "version": "17.6.3", "status": "affected" }, { "version": "17.6.1y", "status": "affected" }, { "version": "17.6.3a", "status": "affected" }, { "version": "17.6.4", "status": "affected" }, { "version": "17.6.5", "status": "affected" }, { "version": "17.6.6", "status": "affected" }, { "version": "17.6.6a", "status": "affected" }, { "version": "17.6.5a", "status": "affected" }, { "version": "17.6.7", "status": "affected" }, { "version": "17.6.8", "status": "affected" }, { "version": "17.6.8a", "status": "affected" }, { "version": "17.7.1", "status": "affected" }, { "version": "17.7.1a", "status": "affected" }, { "version": "17.7.2", "status": "affected" }, { "version": "17.10.1", "status": "affected" }, { "version": "17.10.1a", "status": "affected" }, { "version": "17.8.1", "status": "affected" }, { "version": "17.8.1a", "status": "affected" }, { "version": "17.9.1", "status": "affected" }, { "version": "17.9.2", "status": "affected" }, { "version": "17.9.1a", "status": "affected" }, { "version": "17.9.3", "status": "affected" }, { "version": "17.9.2a", "status": "affected" }, { "version": "17.9.3a", "status": "affected" }, { "version": "17.9.4", "status": "affected" }, { "version": "17.9.5", "status": "affected" }, { "version": "17.9.4a", "status": "affected" }, { "version": "17.9.5a", "status": "affected" }, { "version": "17.9.6", "status": "affected" }, { "version": "17.9.5e", "status": "affected" }, { "version": "17.9.5f", "status": "affected" }, { "version": "17.11.1", "status": "affected" }, { "version": "17.11.1a", "status": "affected" }, { "version": "17.12.1", "status": "affected" }, { "version": "17.12.1a", "status": "affected" }, { "version": "17.12.2", "status": "affected" }, { "version": "17.12.3", "status": "affected" }, { "version": "17.12.4", "status": "affected" }, { "version": "17.12.3a", "status": "affected" }, { "version": "17.12.4a", "status": "affected" }, { "version": "17.12.4b", "status": "affected" }, { "version": "17.13.1", "status": "affected" }, { "version": "17.13.1a", "status": "affected" }, { "version": "17.14.1", "status": "affected" }, { "version": "17.14.1a", "status": "affected" }, { "version": "17.15.1", "status": "affected" }, { "version": "17.15.1a", "status": "affected" } ] } ] } } }
