GHSA-F3QQ-49M6-RW8F Lemur: SSRF protection in certificate revocation checking bypassable via HTTP redirects and DNS rebinding (incomplete fix for GHSA-54vg-pfh7-jq95)

Summary The SSRF mitigation added for GHSA-54vg-pfh7-jq95 validaterevocationurl in lemur /certificates/verify.py can be bypassed. An operator-role user who uploads a certificate with attacker-controlled CRL/OCSP extensions can still make Lemur reach internal destinations RFC1918, loopback,...
