Summary
NGINX ngx_http_charset_module vulnerability
Details

NGINX Plus and NGINX Open Source have a vulnerability in the ngxhttpcharsetmodule module. When content is served or proxied through a location block with both sourcecharset utf-8; and a charset directive (for example, charset koi8-r;) configured, remote, unauthenticated attackers can send requests (in conjunction with conditions beyond their control) to cause a heap buffer over-read in the NGINX worker process, leading to limited disclosure of memory or a restart.

Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
