Disable unneeded protocols in curl #2298
curl's Gentoo ebuild unconditionally enables protocols we don't need, such as dict, Gopher, IMAP, POP3, SMTP, and Telnet. It'd be nice to turn those protocols off to reduce our exposure to curl CVEs. We may not want to move curl to coreos-overlay just to disable them, but perhaps we could push a patch upstream to gate those protocols behind USE flags, and then disable them in CL.
Thank you for reporting this issue. Unfortunately, we don't think we'll end up addressing it in Container Linux.
We're now working on Fedora CoreOS, the successor to Container Linux, and we expect most major development to occur there instead. Meanwhile, Container Linux will be fully maintained into 2020 but won't see many new features. We appreciate your taking the time to report this issue and we're sorry that we won't be able to address it.
