Does php_openssl enavled causes vulnerabilities to the site?

Hi Experts!

Since I'm using Office365 server to send e-mails by the site (using PHPMailer) I had to enable the
extension  = php_openssl

to get the job done.

Does it causes vulnerabilities to the site?
If so, what must be done to remedy?

Thanks in advance.

Quite the opposite. OpenSSL enables PHPMailer to use encryption when talking to Office365, so it doesn't expose your id and password in network traffic.

Maybe I'm misconcepting something and the subjects are diferents from each other.  Could you confirm?

That was a big problem at the time, but it was fixed long, long ago. Use a recent openssl version and you'll be fine. Not using SSL is a far bigger risk than using a buggy SSL. If you have any doubts about your config, run the Qualys SSL tester on your site.

Since I'm using a homologation server I couldn't use the link.

Could you give a look at openSSL library that came in PHP instalation?

Marcus BointonCommented:
Now that's far more of a risk - you're running some very old versions of packages that have known security issues, and some of them are now so old that no more security patches are being produced - PHP 5.3.4 was released in 2010 and support ended a year ago. I don't know what you mean by a homologation server (it looks like you're using the WAMP bundle), but you should upgrade as soon as you can.
