OS X Certificate Viewer busy hangs for minutes when viewing certificate with 1000 SubjectAltNames

Project Member Reported by aerotwist@chromium.org, Mar 22 2017

Issue description

Go to csstriggers.com
Open DevTools => Security => View Certificate
Chrome hangs for multiple minutes (stable and 59.0.3048.0)
 
Components: UI>Browser>CertificateViewer
No problem on Windows; crashes in Safari too.

The certificate contains 999 SubjectAltNames which seems likely to be an issue.
Can't repro on Linux either. Do you have a crash id?
For me, it looks to be a busy-hang rather than a crash.

I see the same problem on 1000-sans.badssl.com. It may be the size of the certificate rather than the SAN count?

It'd be interesting if this was a regression after 10.9 or existed then as well.
On https://1000-sans.badssl.com, after ~10 minutes of pegging a CPU on a 2015 MacBook (2.2ghz i7), the native certificate panel appears, but it seems to hang for multiple seconds as you interact with it.
Summary: OS X Certificate Viewer busy hangs for minutes when viewing certificate with 1000 SubjectAltNames (was: Requesting certificate in DevTools crashes Chrome)

Given that this also crashes in Safari, this sounds like a bug in the native cert viewer.
