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.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-125","CWE-345"],"vendors":[],"products":[],"references":[{"url":"https://github.com/MidnightBSD/mport/security/advisories/GHSA-qc2f-2j7j-m3r7","tags":[]}],"exploitRefs":[{"url":"https://github.com/MidnightBSD/mport/security/advisories/GHSA-qc2f-2j7j-m3r7","tags":[]}],"hasPoc":true,"ai":null}
