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.
| System | Port | Version | State | Fixed |
|---|---|---|---|---|
| DragonFly | security/openvpn | 2.6.14 | vulnerable since 2026-04-22 | |
| OpenBSD | net/openvpn | 2.7.8 | out of range, by version | |
| NetBSD | net/openvpn | 2.7.7 | not listed | |
| MidnightBSD | security/openvpn | 2.6.14_1 | in range, by version | |
| FreeBSD | security/openvpn | 2.7.8 | fixed | (70 days after) |
