This vulnerability is due to the improper handling of large fragmented tunnel protocol packets. One example of a tunnel protocol is Generic Routing Encapsulation (GRE). An attacker could exploit this vulnerability by sending crafted fragmented packets to an affected system. A successful exploit could allow the attacker to cause the affected system to reload, resulting in a DoS condition. Note: Only traffic directed to the affected system can be used to exploit this vulnerability."}], "lastModified": "2023-11-07T04:05:56.520", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:o:cisco:ios_xe:17.9.1:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "5B0C2129-8149-4362-827C-A5494C9D398B"}, {"criteria": "cpe:2.3:o:cisco:ios_xe:17.9.1a:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "7452C7E9-6241-42C5-9A7F-13C0BD38A2B4"}, {"criteria": "cpe:2.3:o:cisco:ios_xe:17.9.1w:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "38C48FC4-5362-4B61-8B8C-7CAFFB81045E"}], "operator": "OR"}]}], "sourceIdentifier": "ykramarz@cisco.com"}
