Critical OpenSSH Vulnerability (CVE-2024-6387)

Hi Fred12 ,

Thank you for reaching out to the community, openssh server on SFOS is not affected.

Hello,

Running the "sshd -v" command while connected to a firewall running SFOS v20 outputs this:

XGS126_XN02_SFOS 20.0.0 GA-Build222# sshd -v
2024-07-04 12:14:51Z unknown option -- v
OpenSSH , OpenSSL 1.1.1q 5 Jul 2022
usage: sshd [-46DdeiqTt] [-C connection_spec] [-c host_cert_file]
 [-E log_file] [-f config_file] [-g login_grace_time]
 [-h host_key_file] [-o option] [-p port] [-u len]
XGS126_XN02_SFOS 20.0.0 GA-Build222#

Now I know that 1.1.1q is the version of OpenSSL but still, it was released back in 2022. It wouldn't be to far fetched to assume that OpenSSH also is running a version from 2022?

Assuming that the build of OpenSSH used in SFOS is vanilla and since all version since 2020 are vulnerable, that would make SFOS's OpenSSH version also vulnerable wouldn't it?

Thank you

Nevermind, an advisory was posted today stating that Sophos products are not affected.
