VAR-201803-1383
Vulnerability from variot - Updated: 2023-12-18 13:48A vulnerability in the Internet Group Management Protocol (IGMP) packet-processing functionality of Cisco IOS XE Software could allow an unauthenticated, adjacent attacker to exhaust buffers on an affected device, resulting in a denial of service (DoS) condition, aka a Memory Leak. The vulnerability is due to the affected software insufficiently processing IGMP Membership Query packets that are sent to an affected device. An attacker could exploit this vulnerability by sending a large number of IGMP Membership Query packets, which contain certain values, to an affected device. A successful exploit could allow the attacker to exhaust buffers on the affected device, resulting in a DoS condition that requires the device to be reloaded manually. This vulnerability affects: Cisco Catalyst 4500 Switches with Supervisor Engine 8-E, if they are running Cisco IOS XE Software Release 3.x.x.E and IP multicast routing is configured; Cisco devices that are running Cisco IOS XE Software Release 16.x, if IP multicast routing is configured. Cisco Bug IDs: CSCuw09295, CSCve94496. Vendors have confirmed this vulnerability Bug ID CSCuw09295 and CSCve94496 It is released as.Service operation interruption (DoS) There is a possibility of being put into a state. The Cisco Catalyst 4500 Switches with Supervisor Engine 8-E is a switch from Cisco. IOSXESoftware is an operating system that runs on Cisco network devices. A resource management error vulnerability exists in the Internet Group Management Protocol (IGMP) packet processing feature in Cisco IOSXE Software, which stems from a failure of the program to adequately process IGMP MembershipQuery packets
