OpenSSL versions 1.0.2 and 1.1.0 have a vulnerability in the handling of recursive ASN.1 structures. Constructed ASN.1 types with a recursive definition (such as can be found in PKCS7) could eventually exceed the stack given malicious input with excessive recursion. This could result in a Denial Of Service attack. There are no such structures used within SSL/TLS that come from untrusted sources so this is considered safe.
