Descriptions

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.

nginx 0.5.6 hasta 1.7.4, cuando utiliza el mismo ssl_session_cache o ssl_session_ticket_key compartido para múltiples servidores, puede reutilizar una sesión SSL en caché para un contexto no relacionado, lo que permite a atacantes remotos con ciertos privilegios realizar ataques de 'confusión de anfitriones virtuales'.

A bug in the experimental SPDY implementation in nginx was found, which might allow an attacker to cause a heap memory buffer overflow in a worker process by using a specially crafted request, potentially resulting in arbitrary code execution. Antoine Delignat-Lavaud and Karthikeyan Bhargavan discovered that 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.
