Summary
Red Hat Security Advisory: containernetworking-plugins security update

Notes

Topic
An update for containernetworking-plugins is now available for Red Hat Enterprise Linux 7 Extras. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
The Container Network Interface (CNI) project consists of a specification and libraries for writing plug-ins for configuring network interfaces in Linux containers, along with a number of supported plug-ins. CNI concerns itself only with network connectivity of containers and removing allocated resources when the container is deleted. Security Fix(es): * HTTP/2: flood using PING frames results in unbounded memory growth (CVE-2019-9512) * HTTP/2: flood using HEADERS frames results in unbounded memory growth (CVE-2019-9514) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
