Limit recursive definition ASN.1 types with OpenSSL update

    • Fully Compatible
    • v3.6, v3.4, v3.2

      Constructed ASN.1 types with a recursive definition (as in PKCS7) could exceed stack given excessive recursion. No such structures within SSL/TLS come from untrusted sources so this is considered safe

      Fixed in OpenSSL 1.1.0h (Affected 1.1.0-1.1.0g).
      Fixed in OpenSSL 1.0.2o (Affected 1.0.2b-1.0.2n).
