We just updated our Dockerfile to set the latest OpenResty Version
OpenResty 220.127.116.11 is a patch release addressing a security vulnerability in the NGINX resolver that may allow an attacker who is able to forge UDP packets from the specified DNS server to cause a 1-byte memory overwrite, resulting in a worker process crash or other unspecified impact. (CVE-2021-23017)
NGINX cores from 0.6.18 to 1.20.0 (included) are affected by this issue. If you are using resolver directive with any previous OpenResty release, upgrade to 18.104.22.168.
This is the second OpenResty release based on the nginx 1.19.3 core.
