CVE-2019-9513

First published: Thu Aug 01 2019(Updated: )

Some HTTP/2 implementations are vulnerable to resource loops, potentially leading to a denial of service. The attacker creates multiple request streams and continually shuffles the priority of the streams in a way that causes substantial churn to the priority tree. This can consume excess CPU.

Remedy

Red Hat Quay 3.0 uses Nginx 1.12 from Red Hat Software Collections. It will be updated once a fixed is released for Software Collections. In the meantime users of Quay can disable http/2 support in Nginx by following these instructions: 1. Copy the Nginx configuration from the quay container to the host $ docker cp 3aadf1421ba3:/quay-registry/conf/nginx/ /mnt/quay/nginx 2. Edit the Nginx configuration, removing http/2 support $ sed -i 's/http2 //g' /mnt/quay/nginx/nginx.conf 3. Restart Nginx with the new configuration mounted into the container, eg: $ docker run --restart=always -p 443:8443 -p 80:8080 --sysctl net.core.somaxconn=4096 -v /mnt/quay/config:/conf/stack:Z -v /mnt/quay/storage:/datastorage -v /mnt/quay/nginx:/quay-registry/config/nginx:Z -d quay.io/redhat/quay:v3.0.3
