Fixed security issues :

  - CVE-2014-0133: nginx:heap-based buffer overflow in SPDY
    implementation

New upstream release 1.4.7 (bnc#869076) (CVE-2014-0133)

*) Security: a heap memory buffer overflow might occur in a worker
process while handling a specially crafted request by
ngx_http_spdy_module, potentially resulting in arbitrary code
execution (CVE-2014-0133). Thanks to Lucas Molas, researcher at
Programa STIC, Fundación Dr. Manuel Sadosky, Buenos Aires,
Argentina.

*) Bugfix: in the 'fastcgi_next_upstream' directive. Thanks
to Lucas Molas.

*) Bugfix: the 'client_max_body_size' directive might not
work when reading a request body using chunked transfer
encoding; the bug had appeared in 1.3.9. Thanks to Lucas
Molas.

*) Bugfix: a segmentation fault might occur in a worker
process when proxying WebSocket connections.

*) Bugfix: the $ssl_session_id variable contained full
session serialized instead of just a session id. Thanks to
Ivan Ristić.

*) Bugfix: client connections might be immediately closed if
deferred accept was used; the bug had appeared in 1.3.15.

*) Bugfix: alerts 'zero size buf in output' might appear in
logs while proxying; the bug had appeared in 1.3.9.

*) Bugfix: a segmentation fault might occur in a worker
process if the ngx_http_spdy_module was used.

*) Bugfix: proxied WebSocket connections might hang right
after handshake if the select, poll, or /dev/poll methods
were used.

*) Bugfix: a timeout might occur while reading client
request body in an SSL connection using chunked transfer
encoding.

*) Bugfix: memory leak in nginx/Windows."
