Vulnerability from variot
Cisco IOS XR 3.8.1 through 4.2.0 does not properly process fragmented packets within the RP-A, RP-B, PRP, and DRP-B route-processor components, which allows remote attackers to cause a denial of service (transmission outage) via (1) IPv4 or (2) IPv6 traffic, aka Bug ID CSCuh30380. Vendors have confirmed this vulnerability Bug ID CSCuh30380 It is released as.By a third party (1) IPv4 Or (2) IPv6 Service disruption through traffic ( Stop sending ) There is a possibility of being put into a state. Cisco IOS XR is a member of the Cisco IOS Software family that uses a microkernel-based operating system architecture. Lead to a denial of service attack. The following processors are affected by this vulnerability: Cisco CRS 16-Slot Line Card Chassis Route Processor (RP-A) Cisco CRS 16-Slot Line Card Chassis Route Processor B (RP-B) Carrier Routing System (CRS) Performance Route Processor (PRP) ) Cisco CRS Distributed Route Processor (DRP-B). Successfully exploiting this issue may allow an attacker to cause a denial-of-service condition. This issue is being tracked by Cisco Bug ID CSCuh30380. The vulnerability stems from the fact that the router processor components (including: RP-A, RP-B, PRP, DRP-B) do not properly process segmented data Bag. A remote attacker could exploit this vulnerability to cause a denial of service (transmission interruption) by sending fragmented packets to an affected system
