By system
1 still vulnerable, 1 fixed. Where VuXML applies (FreeBSD, DragonFly, FreeBSD's derivatives) a port is vulnerable while its version is in a range; pkgsrc says itself whether it lists a CVE of this advisory; OpenBSD and MidnightBSD keep no list this site reads, so their row is only an estimate: FreeBSD's ranges applied to upstream's version.

| DragonFly | net/rabbitmq-c | 0.15.0 | vulnerable since 2026-10-06 | |
| OpenBSD | net/rabbitmq-c | 0.18.1 | out of range, by version | |
| NetBSD | net/rabbitmq-c | 0.15.0 | not listed | |
