Description :
Nginx is a web server and a reverse proxy server for HTTP, SMTP, POP3 and

--------------------------------------------------------------------------------Update Information:

Fix log permissions issue  ----  Security: 1-byte memory overwrite 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 worker process crash or, potentially, arbitrary code
execution        (CVE-2021-23017).
