Curl segfaults when failing to get public key from SSL certificate

[tysg]

Version: 8.12.0

curl/lib/vtls/openssl.c

Line 4524 in 9391fc1

current_pkey = X509_get0_pubkey(current_cert);

X509_get0_pubkey can fail and return null
https://docs.openssl.org/1.1.1/man3/X509_get_pubkey/#return-values

In this case, curl will segfault at

curl/lib/vtls/openssl.c

Line 4537 in 9391fc1

type_name = EVP_PKEY_get0_type_name(current_pkey);

$ openssl x509 -in /tmp/cert.pem  -pubkey
