Published Sep 6, 2022
·
Updated

A closing HTTP/2 server connection could hang forever waiting for a clean shutdown that was preempted by a subsequent fatal error. This failure mode could be exploited to cause a denial of service.

Other sources

A flaw was found in the golang package. In net/http in Go, attackers can cause a denial of service because an HTTP/2 connection can hang during closing if a fatal error preempts the shutdown.

Golang Go is vulnerable to a denial of service, caused by a flaw in net/http. By sending a specially-crafted request, a remote attacker could exploit this vulnerability to cause a closing HTTP/2 server connection to hang, and results in a denial of service condition.

IBM

In net/http in Go before 1.18.6 and 1.19.x before 1.19.1 attackers can cause a denial of service because an HTTP/2 connection can hang during closing if shutdown were preempted by a fatal error.

Microsoft

In net/http in Go before 1.18.6 and 1.19.x before 1.19.1, attackers can cause a denial of service because an HTTP/2 connection can hang during closing if shutdown were preempted by a fatal error.
