Description

An update for the go-toolset:rhel8 module is now available for Red Hat Enterprise Linux 8.

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.

Go Toolset provides the Go programming language tools and libraries. Go is alternatively known as golang.

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.

Bug Fix(es) :

  • Failure trying to conntect to image registry using TLS when buildah is compiled with FIPS mode (BZ#1743169)
