The memory consumption may negatively impact other processes that are running on the device. These vulnerabilities are due to the incorrect handling of IGMP packets. An attacker could exploit these vulnerabilities by sending crafted IGMP traffic to an affected device. A successful exploit could allow the attacker to immediately crash the IGMP process or cause memory exhaustion, resulting in other processes becoming unstable. These processes may include, but are not limited to, interior and exterior routing protocols. Cisco will release software updates that address these vulnerabilities.","2020-09-23",8.6,"v3.1","High",0.0332,{"cveId":26,"description":27,"publishedDate":28,"cvssScore":29,"cvssVersion":22,"severity":23,"isKev":30,"epssScore":31},"CVE-2021-34718","A vulnerability in the SSH Server process of Cisco IOS XR Software could allow an authenticated, remote attacker to overwrite and read arbitrary files on the local device.
