A race condition flaw was found in Go. The incoming requests body weren't closed after the handler panic and as a consequence this could lead to ReverseProxy crash. The highest threat from this vulnerability is to Availability. golang: net/http/httputil: panic due to racy read of persistConn after handler panic * In Red Hat OpenStack Platform, because the flaw has a lower impact and the fix would require a substantial amount of development, no update will be provided at this time for the impacted RHOSP packages. * In Service Telemetry Framework, because the flaw has a lower impact and the package is not directly used by STF1.3, no update will be provided at this time for the STF1.3 sg-core-container. Additionally, because Service Telemetry Framework1.2 will be retiring soon, no update will be provided at this time for the STF1.2 smart-gateway-container. The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.
