CVE-2018-0739 (OpenSSL advisory) [Moderate severity] 27 March 2018: 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. Reported by OSS-fuzz. This patch also entirely removes support for SSLv3. The patch to disable it didn't apply and since nobody has been using this before, we will not compile it into OpenSSL any more.
