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 | graphics/openexr | 3.3.4 | vulnerable since 2026-04-02 | |
| OpenBSD | graphics/openexr | 3.5.2 | out of range, by version | |
| NetBSD | graphics/openexr | 3.4.15 | not listed | |
| MidnightBSD | graphics/openexr | 3.1.5 | in range, by version | |
| FreeBSD | graphics/openexr | 3.4.16 | fixed | (134 days after) |
