BSD Portsc-ares -- Use After Free
· CVE-2025-62408 · VuXML entry
https://github.com/c-ares/c-ares/security/advisories/GHSA-jq53-42q6-pqr5 reports: c-ares is an asynchronous resolver library. Versions 1.32.3 through 1.34.5 terminate a query after maximum attempts when using read_answer() and process_answer(), which can cause a Denial of Service. This issue is fixed in version 1.34.6.
Affected versions
- c-ares >= 1.32.3 < 1.34.6
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 |
|---|---|---|---|---|
| FreeBSD | dns/c-ares | 1.34.9 | fixed | (215 days after) |
| MidnightBSD | dns/c-ares | 1.34.9 | out of range, by version | |
| DragonFly | dns/c-ares | 1.34.4_1 | vulnerable since 2025-12-09 |
