Vulnerability #1: GO-2025-4011
    Parsing DER payload can cause memory exhaustion in encoding/asn1
  More info: https://pkg.go.dev/vuln/GO-2025-4011
  Standard library
    Found in: encoding/asn1@go1.24.6
    Fixed in: encoding/asn1@go1.24.8
    Example traces found:
Error:       #1: ec_key_pair.go:471:37: ocrypto.GetECKeySize calls x509.ParsePKIXPublicKey, which calls asn1.Unmarshal

  More info: https://pkg.go.dev/vuln/GO-2025-4010
  Standard library
    Found in: net/url@go1.24.6
    Fixed in: net/url@go1.24.8
    Example traces found:
Error:       #1: ec_key_pair.go:318:37: ocrypto.ECPubKeyFromPem calls x509.ParseCertificate, which eventually calls url.Parse

Vulnerability #3: GO-2025-4009
    Quadratic complexity when parsing some invalid inputs in encoding/pem
  More info: https://pkg.go.dev/vuln/GO-2025-4009
  Standard library
    Found in: encoding/pem@go1.24.6
    Fixed in: encoding/pem@go1.24.8
    Example traces found:
Error:       #1: ec_key_pair.go:466:24: ocrypto.GetECKeySize calls pem.Decode

Vulnerability #4: GO-2025-4007
    Quadratic complexity when checking name constraints in crypto/x509
  More info: https://pkg.go.dev/vuln/GO-2025-4007

    Example traces found:
Error:       #1: ec_key_pair.go:433:53: ocrypto.ECPrivateKeyInPemFormat calls x509.MarshalPKCS8PrivateKey
Error:       #2: ec_key_pair.go:449:39: ocrypto.ECPublicKeyInPemFormat calls x509.MarshalPKIXPublicKey
Error:       #3: ec_key_pair.go:318:37: ocrypto.ECPubKeyFromPem calls x509.ParseCertificate
Error:       #4: asym_decryption.go:57:37: ocrypto.FromPrivatePEMWithSalt calls x509.ParseECPrivateKey
Error:       #5: asym_decryption.go:52:40: ocrypto.FromPrivatePEMWithSalt calls x509.ParsePKCS1PrivateKey
