If you are have a web server facing the public internet, turn off SSLv2 immediately. OpenSSL 1.0.2g has the fix but it will take a while to drip down to the repos as it brings with it an ABI change. The vulnerability is so bad[1], it doesn't only have a CVE number, CVE-2016-0800[4], but a name and its own website: HTTPS DROWN[1][2][3]. One third of all public web servers are open to attack[2][3] and OpenSSL may not be the only crypto library affected[1][4].
