Prior to 2.7.8, ping() in libmport/ping.c accepted ICMP replies without validating icmp_id or icmp_seq and parsed the reply using a fixed IP-header offset instead of ip_hl. A network attacker able to inject or spoof visible ICMP replies could influence mirror latency selection, while a malformed packet carrying IP options could shift the ICMP header and trigger an out-of-bounds read. This issue is fixed in version 2.7.8.","state":0,"publishedAt":"2026-09-17T16:59:52.147+00:00","modifiedAt":"2026-09-24T20:55:22.592+00:00","affected":[{"ecosystem":"Vendor product","name":"mport","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"MidnightBSD\",\n                    \"product\": \"mport\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 2.7.8\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:A/AC:L/AT:P/PR:N/UI:N/VC:N/VI:L/VA:L/SC:N/SI:N/SA:N","score":2.3,"severity":"LOW"}],"references":["https://github.com/MidnightBSD/mport/security/advisories/GHSA-qc2f-2j7j-m3r7"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-54579","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-54579","identifiers":["CVE-2026-54579"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
