CVE-2019-1749 A vulnerability in the ingress traffic validation of Cisco IOS XE Software for Cisco Aggregation Services Router (ASR)…

Description

A vulnerability in the ingress traffic validation of Cisco IOS XE Software for Cisco Aggregation Services Router (ASR) 900 Route Switch Processor 3 (RSP3) could allow an unauthenticated, adjacent attacker to trigger a reload of an affected device, resulting in a denial of service (DoS) condition. The vulnerability exists because the software insufficiently validates ingress traffic on the ASIC used on the RSP3 platform. An attacker could exploit this vulnerability by sending a malformed OSPF version 2 (OSPFv2) message to an affected device. A successful exploit could allow the attacker to cause a reload of the iosd process, triggering a reload of the affected device and resulting in a DoS condition.
