Detail

Cisco IOS XR Software Releases 3.8.3, 3.8.4, and 3.9.1 are affected by a vulnerability that an unauthenticated, remote user can trigger by sending specific IP version 4 (IPv4) packets to or through an affected device.

Successful exploitation could cause the NetIO process to restart. Under a sustained attack, the Cisco CRS Modular Services Card (MSC) on a Cisco Carrier Routing System (CRS) or a Line Card on a Cisco 12000 Series Router or Cisco ASR 9000 Series Aggregation Services Router will reload.

Cisco has released free Software Maintenance Units (SMU) that address this vulnerability.

There are no workarounds for this vulnerability.
