Mountain brake, Raf :-)
Fixed yesterday, already running on productions (on my side) ;-)

Subject: Re: ssl bump and chrome 58
[This sender failed our fraud detection checks and may not be who they appear to be. Learn about spoofing at http://aka.ms/LearnAboutSpoofing]
Hello all,
The following steps give in Chrome 58 the "Your connection is not private" error with "NET::ERR_CERT_COMMON_NAME_INVALID" and "missing_subjectAltName" error:
(peek-an-splice bumping squid 3.5.23_1 as in https://docs.diladele.com/howtos/build_squid_ubuntu16/index.html)
1. Open Chrome 58+
2. Type some non existing domain name like "https://www.asdlajsdfl.com"; (note the httpS:// schema) 3. See the missing_subjectAltName error.
Correct behavior would be Squid generating faked certificate for the domain name "www.asdlajsdfl.com" *with* subjectAltName extension set to "www.asdlajsdfl.com".
So question is - does anyone know if this is already existing bug or shall I file one?
May be it is a feature?
Best regards,
Rafael

I've tested the registry setting and it worked out. You can copy the below lines in a .reg file and execute it.
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome]
"EnableCommonNameFallbackForLocalAnchors"=dword:00000001

Hello together,
here is a workaround that you could use in the meanwhile.
https://www.chromium.org/administrators/policy-list-3#EnableCommonName
FallbackForLocalAnchors
Source:
https://www.chromium.org/administrators/policy-list-3#EnableCommonName
FallbackForLocalAnchors
BEGIN
EnableCommonNameFallbackForLocalAnchors
Whether to allow certificates issued by local trust anchors that are
missing the subjectAlternativeName extension
Data type:
Boolean [Windows:REG_DWORD]
Windows registry location:
Software\Policies\Google\Chrome\EnableCommonNameFallbackForLocalAnchor
s
Mac/Linux preference name:
EnableCommonNameFallbackForLocalAnchors
Android restriction name:
EnableCommonNameFallbackForLocalAnchors
Supported on:
Google Chrome (Linux, Mac, Windows) since version 58 until
version 65
Google Chrome OS (Google Chrome OS) since version 58 until
version 65
Google Chrome (Android) since version 58 until version 65
Supported features:
Dynamic Policy Refresh: Yes, Per Profile: No
Description:
When this setting is enabled, Google Chrome will use the
commonName of a server certificate to match a hostname if the
certificate is missing a subjectAlternativeName extension, as long as
it successfully validates and chains to a locally-installed CA
certificates.
Note that this is not recommended, as this may allow bypassing the
nameConstraints extension that restricts the hostnames that a given
certificate can be authorized for.
If this policy is not set, or is set to false, server certificates
that lack a subjectAlternativeName extension containing either a DNS
name or IP address will not be trusted.
Example value:
0x00000000 (Windows), false (Linux), false (Android), <false />
(Mac)

Hello together,
Suddenly I am facing the same issue when users Chrome has been
updated to V58. I am running Squid 3.5.23.
This is the reason:
https://www.thesslstore.com/blog/security-changes-in-chrome-58/
Short: Common Name Support Removed in Chrome 58 and Squid does not
create certs with DNS-Alternatives names in it. Because of that it
fails.
Chrome says:
1. Subject Alternative Name Missing - The certificate for this site
does not contain a Subject Alternative Name extension containing a
domain name or IP address.
2. Certificate Error - There are issues with the site's certificate
chain (net::ERR_CERT_COMMON_NAME_INVALID).
Can we get Squid to add the DNS-Alternative Name to the generated
certs? Since this is what I believe is now required in Chrome 58+
Best regards,
Enrico

I see no problem with it on all five SSL Bump-aware servers with new
Chrome. So fare so good.

Hi,
I have squid setup with ssl bump which worked fine, but since I
updated chrome to 58 it won't display any https sites, throwing
NTT:ERR_CERT_COMMON_NAME_INVALID. https sites still work in
previous chrome version, as well as in IE.
Anything I can do in squid config to get ssl-bumped sites in chrome
again?
Thank you in advance,
