Vulnerability from variot
Cisco IOS XE 3.4 before 3.4.2S and 3.5 before 3.5.1S on 1000 ASR devices allows remote attackers to cause a denial of service (device reload) via malformed ICMP error packets associated with a (1) TCP or (2) UDP session that is under inspection by the Zone-Based Firewall (ZBFW) component, aka Bug ID CSCtt26470. Cisco ASR 1000 Runs on series devices Cisco IOS XE There is a service disruption ( Device reload ) There are vulnerabilities that are put into a state. Cisco IOS is the interconnected network operating system used on most Cisco system routers and network switches. A security vulnerability exists in the Cisco IOS XE's Zone-Based Firewall (ZBFW) TCP or UDP functionality. Cisco IOS XE is prone to a remote denial-of-service vulnerability. Successful exploits may allow an attackers to cause a reload of the affected devices, denying service to legitimate users. This issue is being tracked by Cisco Bug ID CSCtt26470
