 Posted: Wed Jul 10, 2024 8:40 pm Post subject: Is Gentoo's SSH vulnerable to regreSSHion? |
 |
|
Hi
Qualys published a regression to openSSH a couple of days ago. I always update my Gentoo systems on Sunday evenings, so I'm fairly up to date.
I stumbled upon the script https://github.com/xaitax/CVE-2024-6387_Check that checks whether an openSSH installtion is still vulnerable or not.
When I test it with my own host, I get this:
| Code: |
$ python /tmp/CVE-2024-6387_Check.py localhost
...
Servers likely vulnerable: 2
[+] Server at ::1 (running SSH-2.0-OpenSSH_9.7)
[+] Server at 127.0.0.1 (running SSH-2.0-OpenSSH_9.7)
...
|
I've made an eix-sync right now but my openssh is up-to-date (=net-misc/openssh-9.7_p1-r6). So the question is: is Gentoo still vulnerable or is this just a false positive because the script only checks the signature against the most common distributions (like debian, ubuntu, rhel, etc)?

Cool, thanks. Yes, then that's a false positive of the tool.

That check is trivial, it just checks whether your version of openssh is affected ( the first formally unaffected is 9.8p1) and if it is whether it was patched, which for the check means in the list of
patched_versions = [
'SSH-2.0-OpenSSH_8.9p1 Ubuntu-3ubuntu0.10',
'SSH-2.0-OpenSSH_9.3p1 Ubuntu-3ubuntu3.6',
'SSH-2.0-OpenSSH_9.6p1 Ubuntu-3ubuntu13.3',
'SSH-2.0-OpenSSH_9.3p1 Ubuntu-1ubuntu3.6',
'SSH-2.0-OpenSSH_9.2p1 Debian-2+deb12u3',
'SSH-2.0-OpenSSH_8.4p1 Debian-5+deb11u3',
'SSH-2.0-OpenSSH_9.7p1 Debian-7',
'SSH-2.0-OpenSSH_9.6 FreeBSD-20240701',
'SSH-2.0-OpenSSH_9.7 FreeBSD-20240701'
]
that distributions, which obviously knows noting about Gentoo. |
