Re: bug in Lynx' SSL certificate validation -> leaks password in clear text via SNI (under some circumstances)

Hi XTaran,

I *ALWAYS* SAID SNI IS A SHIT THING […]

Don't blame the messenger. ;-)

Not blaming you in the slightest, rather the contrary, thanks for
vindicating me ☻☺

Other browsers also need checking.

Good idea.
[…]
I didn't find any such issue in any of these tools. All cases verified
via Wireshark's "follow TCP stream" against an Apache 2.4.48 (from
Debian Unstable as well).

But yeah, there are probably many more to check. But so far it looks
like a lynx-specific issue.

Good to know.

Thanks for the detective work,

You're welcome. Thanks for stumbling over this issue and triggering my
digging. :-)

Heh, I know the feeling. *adds more mksh commits because a user is
porting it to another weird hobbyist OS…*

bye,
