Updates to versions of OpenSSL (Secure Sockets Layer) are expected on March 19 to address newly discovered vulnerabilities. The OpenSSL team has not yet provided information about the vulnerabilities, but has announced that one of them is classified as "high" severity.

IIA is monitoring the situation and expects to issue an alert that instructs those responsible for U-M systems running OpenSSL to update to the new versions. Here are our current recommendations:
