Description

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.

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.
