Vulnerability from variot
The IKEv2 implementation in Cisco IOS 15.0 through 15.6 and IOS XE 3.3 through 3.17 allows remote attackers to cause a denial of service (device reload) via fragmented packets, aka Bug ID CSCux38417. Both Cisco IOS and IOSXESoftware are operating systems developed by Cisco for its network devices. A security vulnerability exists in the fragmentation code for the IKE2 version in CiscoIOS and IOSXESoftware because the program failed to properly handle fragmented IKEv2 packets. A remote attacker could exploit the vulnerability by sending a specially crafted UDP packet to cause a denial of service. This issue is being tracked by Cisco Bug ID CSCux38417. Note: The traffic only to the directed system can be exploited by this issue. The vulnerability can be triggered by IPv4 and IPv6 traffic

"data": "The IKEv2 implementation in Cisco IOS 15.0 through 15.6 and IOS XE 3.3 through 3.17 allows remote attackers to cause a denial of service (device reload) via fragmented packets, aka Bug ID CSCux38417. Both Cisco IOS and IOSXESoftware are operating systems developed by Cisco for its network devices. A security vulnerability exists in the fragmentation code for the IKE2 version in CiscoIOS and IOSXESoftware because the program failed to properly handle fragmented IKEv2 packets. A remote attacker could exploit the vulnerability by sending a specially crafted UDP packet to cause a denial of service. \nThis issue is being tracked by Cisco Bug ID CSCux38417. \nNote: The traffic only to the directed system can be exploited by this issue. The vulnerability can be triggered by IPv4 and IPv6 traffic",
