nginx 1.1.19 *) 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.
