CVE-2026-54579
Severity not reportedData quality: partial.
Some fields were not provided by the source.
mport is the MidnightBSD Package Manager.
mport is the MidnightBSD Package Manager. 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.
