Changes with nginx 1.8.1 26 Jan 2016 ``` *) Security: invalid pointer dereference might occur during DNS ``` server response processing if the “resolver” directive was used, allowing an attacker who is able to forge UDP packets from the DNS server to cause segmentation fault in a worker process (CVE-2016-0742). ``` *) Security: use-after-free condition might occur during CNAME ``` response processing if the “resolver” directive was used, allowing an attacker who is able to trigger name resolution to cause segmentation fault in a worker process, or might have potential other impact (CVE-2016-0746). ``` *) Security: CNAME resolution was insufficiently limited if the "resolver" directive was used, allowing an attacker who is able ``` to trigger arbitrary name resolution to cause excessive resource consumption in worker processes (CVE-2016-0747). ``` *) Bugfix: the "proxy_protocol" parameter of the "listen" directive ``` did not work if not specified in the first “listen” directive for a listen socket. ``` *) Bugfix: nginx might fail to start on some old Linux variants; the ``` bug had appeared in 1.7.11. ``` *) Bugfix: a segmentation fault might occur in a worker process if ``` the “try\_files” and “alias” directives were used inside a location given by a regular expression; the bug had appeared in 1.7.1. ``` *) Bugfix: the "try_files" directive inside a nested location given ``` by a regular expression worked incorrectly if the “alias” directive was used in the outer location. ``` *) Bugfix: "header already sent" alerts might appear in logs when ``` using cache; the bug had appeared in 1.7.5. ``` *) Bugfix: a segmentation fault might occur in a worker process if different ssl_session_cache settings were used in different ``` virtual servers. ``` *) Bugfix: the "expires" directive might not work when using ``` variables. ``` *) Bugfix: if nginx was built with the ngx_http_spdy_module it was possible to use the SPDY protocol even if the "spdy" parameter of ``` the “listen” directive was not specified. – Maxim D.
