CVE-2019-9511: Some HTTP/2 implementations are vulnerable to window size manipulation and stream prioritization manipulation, potentially leading to a denial of service

First published: Tue Aug 13 2019(Updated: )

A flaw was found in HTTP/2. An attacker can request a large amount of data by manipulating window size and stream priority to force the server to queue the data in 1-byte chunks. Depending on how efficiently this data is queued, this queue can consume excess CPU, memory, or both, leading to a denial of service. The highest threat from this vulnerability is to system availability.

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
