CentOS 8: 2022-a47be0a2c1 Critical Risk: Apache Buffer Overflow

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

IMAP protocols, with a strong focus on high concurrency, performance and low

memory usage.

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).
