By system
1 still vulnerable, 2 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 |
|---|---|---|---|---|
| FreeBSD | comms/lrzsz | 0.12.20_7 | fixed | |
| OpenBSD | comms/lrzsz | 0.12.20p4 | out of range, by version | |
| NetBSD | comms/lrzsz | 0.12.20nb1 | listed since 2024-11-08 | |
| MidnightBSD | comms/lrzsz | 0.12.20_4 | out of range, by version | |
