‘Drown’ Vulnerability in SSLv2 and TLS.

Drown SSL TLSThis week sees a new vulnerability in SSLv2 and TLS.

Matthew Green does a great job in explaining all about this so I won’t attempt to regurgitate his excellent explanation, other than to highlight the issue and to say this doesn’t look good at all and I encourage you to read his blog and take note of this vulnerability:


This just highlights that fact that when a penetration tester tells you you still have SSL issues present on your sever you should definitely look into doing something about it as described by myself here: https://www.adamcouch.co.uk/2015/09/10/changing-ssl-tls-cipher-suites-in-windows-and-linux/
