CVE-2026-54579

mport mirror-selection ping accepts insufficiently validated ICMP replies

Published: Sep 17, 2026Updated: Sep 24, 2026 Sources: CVE List NVDCWE-125

N/ACVSS

NVD MITRE

Description

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.
