ASA-2019-00520 – nginx: Excessive memory usage in HTTP/2 with zero length headers
Several security issues were identified in nginx HTTP/2 implementation, which might cause excessive memory consumption and CPU usage (CVE-2019-9511, CVE-2019-9513, CVE-2019-9516). The issues affect nginx compiled with the ngx_http_v2_module (not compiled by default) if the "http2" option of the "listen" directive is used in a configuration file.
ASA-2019-00519 – nginx: Excessive CPU usage in HTTP/2 with priority changes
Several security issues were identified in nginx HTTP/2 implementation, which might cause excessive memory consumption and CPU usage (CVE-2019-9511, CVE-2019-9513, CVE-2019-9516). The issues affect nginx compiled with the ngx_http_v2_module (not compiled by default) if the "http2" option of the "listen" directive is used in a configuration file.

ASA-2018-00032 – nginx: Infinite loop in a worker process
A security issue was identified in the ngx_http_mp4_module, which might allow an attacker to cause infinite loop in a worker process, cause a worker process crash, or might result in worker process memory disclosure by using a specially crafted mp4 file. The issue only affects nginx if it is built with the ngx_http_mp4_module (the module is not built by default) and the "mp4" directive is used in the configuration file. Further, the attack is only possible if an attacker is able to trigger processing of a specially crafted mp4 file with the ngx_http_mp4_module.
ASA-2018-00031 – nginx: Excessive CPU usage
One security issue was identified in nginx HTTP/2 implementation, which might cause excessive CPU usage. The issue affect nginx compiled with the ngx_http_v2_module (not compiled by default) if the "http2" option of the "listen" directive is used in a configuration file.
ASA-2018-00030 – nginx: Excessive memory consumption
One security issue was identified in nginx HTTP/2 implementation, which might cause excessive memory consumption. The issue affect nginx compiled with the ngx_http_v2_module (not compiled by default) if the "http2" option of the "listen" directive is used in a configuration file.
