BSD Portsopenvpn -- too long a username or password from a client can confuse openvpn servers
Frank Lichtenheld reports: [OpenVPN v2.6.13 ...] improve server-side handling of clients sending usernames or passwords longer than USER_PASS_LEN - this would not result in a crash, buffer overflow or other security issues, but the server would then misparse incoming IV variables and produce misleading error messages.
Affected versions
- openvpn < 2.6.13
By system
0 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 |
|---|---|---|---|---|
| DragonFly | security/openvpn | 2.6.14 | fixed | |
| OpenBSD | net/openvpn | 2.7.8 | out of range, by version | |
| NetBSD | net/openvpn | 2.7.7 | not listed | |
| MidnightBSD | security/openvpn | 2.6.14_1 | out of range, by version | |
| FreeBSD | security/openvpn | 2.7.8 | fixed | (530 days after) |
