Name of the Vulnerable Software and Affected Versions Traefik versions prior to 2.8.8 Traefik versions prior to 2.9.0-rc5

Description There is a potential issue in Traefik managing HTTP/2 connections. A closing HTTP/2 server connection could hang forever because of a subsequent fatal error. This failure mode could be exploited to cause a denial of service.

Recommendations For versions prior to 2.8.8, update to version 2.8.8 or later. For versions prior to 2.9.0-rc5, update to version 2.9.0-rc5 or later. As a temporary workaround, consider restricting the use of HTTP/2 connections until a patch is applied.
