The vulnerability allows a remote non-authenticated attacker to manipulate data.

nginx 0.5.6 through 1.7.4, when using the same shared ssl_session_cache or ssl_session_ticket_key for multiple servers, can reuse a cached SSL session for an unrelated context, which allows remote attackers with certain privileges to conduct "virtual host confusion" attacks.

Mitigation

Install updates from vendor's repository.
