Updated nginx package fixes security vulnerabilities:

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 (CVE-2014-0133).

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 (CVE-2014-3616).
