a heap-based buffer overflow, causing a denial of service or potential
arbitrary code execution.

relied only on the application's self-reported version number.");

    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."

in a worker process by using a specially crafted request, potentially
resulting in arbitrary code execution (CVE-2014-0133).

The problem affects nginx 1.3.15 - 1.5.11, compiled with the
ngx_http_spdy_module module (which is not compiled by default) and
without --with-debug configure option, if the 'spdy' option of the
'listen' directive is used in a configuration file.

The problem is fixed in nginx 1.5.12, 1.4.7."

    A bug in the SPDY implementation in nginx was found which might cause a
      heap memory buffer overflow in a worker process by using a specially
      crafted request. The SPDY implementation is not enabled in default
      configurations.
  
Impact :

    A remote attacker could cause execution of arbitrary code by using a
      specially crafted request.
  
Workaround :

    Disable the spdy module in NGINX_MODULES_HTTP."
