Subject: Re: CVE-2024-6387: RCE in OpenSSH's server, on
 glibc-based Linux systems

Damian, in general when there is incorrect data on any of Red Hat's CVE
pages the best place to request a fix is secalert@...hat.com.

In this case we are paying attention to this mailing list and have
incorporated some suggestions. I can help address any remaining cleanups.

Has OpenSSH ever considered becoming a CNA?
