annotate src/core/ngx_radix_tree.h @ 670:ad45b044f1e5 NGINX_1_1_19
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.
