"This version update for nginx to 1.2.9 includes a security fix and
several bugfixes and feature enhancements. (bnc#821184)

*) Security: contents of worker process memory might be sent to a
client if HTTP backend returned specially crafted response
(CVE-2013-2070); the bug had appeared in 1.1.4.

  - changes with 1.2.8 :

    *) Bugfix: new sessions were not always stored if the
    'ssl_session_cache shared' directive was used and there
    was no free space in shared memory.

    *) Bugfix: responses might hang if subrequests were used
    and a DNS error happened during subrequest processing.

    *) Bugfix: in the ngx_http_mp4_module.

    *) Bugfix: in backend usage accounting.

  - changes with nginx 1.2.7

    *) Change: now if the 'include' directive with mask is
    used on Unix systems, included files are sorted in
    alphabetical order.

    *) Change: the 'add_header' directive adds headers to
    201 responses.

    *) Feature: the 'geo' directive now supports IPv6
    addresses in CIDR notation.

    *) Feature: the 'flush' and 'gzip' parameters of the
    'access_log' directive.

    *) Feature: variables support in the 'auth_basic'
    directive.

    *) Feature: the $pipe, $request_length, $time_iso8601,
    and $time_local variables can now be used not only in
    the 'log_format' directive.

    *) Feature: IPv6 support in the ngx_http_geoip_module.

    *) Bugfix: nginx could not be built with the
    ngx_http_perl_module in some cases.

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

    *) Bugfix: nginx could not be built on MacOSX in some
    cases.

    *) Bugfix: the 'limit_rate' directive with high rates
    might result in truncated responses on 32-bit platforms.

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

    *) Bugfix: a '100 Continue' response was issued with
    '413 Request Entity Too Large' responses.

    *) Bugfix: the 'image_filter',
    'image_filter_jpeg_quality' and 'image_filter_sharpen'
    directives might be inherited incorrectly.

    *) Bugfix: 'crypt_r() failed' errors might appear if the
    'auth_basic' directive was used on Linux.

    *) Bugfix: in backup servers handling.

    *) Bugfix: proxied HEAD requests might return incorrect
    response if the 'gzip' directive was used.

    *) Bugfix: a segmentation fault occurred on start or
    during reconfiguration if the 'keepalive' directive was
    specified more than once in a single upstream block.

    *) Bugfix: in the 'proxy_method' directive.

    *) Bugfix: a segmentation fault might occur in a worker
    process if resolver was used with the poll method.

    *) Bugfix: nginx might hog CPU during SSL handshake with
    a backend if the select, poll, or /dev/poll methods were
    used.

    *) Bugfix: the '[crit] SSL_write() failed (SSL:)' error.

    *) Bugfix: in the 'fastcgi_keep_conn' directive."
