Changes with nginx 1.1.19 12 Apr 2012
*) Security: specially crafted mp4 file might allow to overwrite memory locations in a worker process if the ngx_http_mp4_module was used, potentially resulting in arbitrary code execution (CVE-2012-2089). Thanks to Matthew Daley.
*) Bugfix: nginx/Windows might be terminated abnormally. Thanks to Vincent Lee.
*) Bugfix: nginx hogged CPU if all servers in an upstream were marked as "backup".
*) Bugfix: the "allow" and "deny" directives might be inherited incorrectly if they were used with IPv6 addresses.
*) Bugfix: the "modern_browser" and "ancient_browser" directives might be inherited incorrectly.
*) Bugfix: timeouts might be handled incorrectly on Solaris/SPARC.
*) Bugfix: in the ngx_http_mp4_module.
