OpenSSL Security Advisory 20180327

Posted Mar 27, 2018

Site openssl.org

OpenSSL Security Advisory 20180327 - 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. Other issues were also addressed.
