+
+     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.
+
+     This issue was reported to OpenSSL on 4th January 2018 by the OSS-fuzz
+     project.
