BSD Ports(lib)expat -- Insufficient entropy
· CVE-2026-41080 · VuXML entry
https://github.com/libexpat/libexpat/pull/1183 reports: libexpat before 2.8.0 uses insufficient entropy, and thus hash flooding can occur via a crafted XML document.
Affected versions
- expat < 2.8.0
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 | textproc/expat2 | 2.7.0 | vulnerable since 2026-04-26 | |
| NetBSD | textproc/expat | 2.8.5 | not listed | |
| MidnightBSD | textproc/expat2 | 2.9.0 | out of range, by version | |
| FreeBSD | textproc/expat2 | 2.9.0 | fixed | (116 days after) |
