A security vulnerability was found in the nginx package.


This is the email that went out in the nginx security advisories list regarding this vulnerability:


A problem with SSL session cache in nginx was identified by Antoine
Delignat-Lavaud. It was possible to reuse cached SSL sessions in
unrelated contexts, allowing virtual host confusion attacks in some
configurations by an attacker in a privileged network position

The problem affects nginx 0.5.6 - 1.7.4 if the same shared
ssl_session_cache and/or ssl_session_ticket_key are used for multiple
server{} blocks.

The problem is fixed in nginx 1.7.5, 1.6.2.
