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 | x11-fonts/libXfont2 | 2.0.6 | vulnerable since 2026-08-07 | |
| MidnightBSD | x11-fonts/libXfont2 | 2.0.9 | out of range, by version | |
| FreeBSD | x11-fonts/libXfont2 | 2.0.9 | fixed | (1 days after) |
