This release of yaSSL fixes a medium security vulnerability. A fix for potential AES side channel leaks is included that a local user monitoring the same CPU core cache could exploit. VM users, hyper-threading users, and users where potential attackers have access to the CPU cache will need to update if they utilize AES.
