Comment(by nickm):

 For logging version numbers, prefer OPENSSL_VERSION_TEXT and
 SSLeay_version(SSLEAY_VERSION), I think.

 And a better message would be IMO "Disabling SSLv3 because this OpenSSL
 version might otherwise be vulnerable to CVE-foo." In other words, make it
 clear that this is a problem that stems from the openssl version, and that
 disabling SSLv3 will solve the problem if it exists.

 This could be at NOTICE, I think.  But I'm not sure it has to be. Others
 can decide.
