CVE-2020-15586: Race Condition

Published Jul 14, 2020
·
Updated

A flaw was found Go's net/http package. Servers using ReverseProxy from net/http in the Go standard library are vulnerable to a data race that results in a denial of service. The highest threat from this vulnerability is to system availability.

Other sources

Go before 1.13.13 and 1.14.x before 1.14.5 has a data race in some net/http servers as demonstrated by the httputil.ReverseProxy Handler because it reads a request body and writes a response at the same time.

— Microsoft

Go before 1.13.13 and 1.14.x before 1.14.5 has a data race in some net/http servers, as demonstrated by the httputil.ReverseProxy Handler, because it reads a request body and writes a response at the same time.

Golang Go is vulnerable to a denial of service, caused by a data race in some net/http servers. By sending specially-crafted HTTP requests, a remote attacker could exploit this vulnerability to cause a denial of service condition.

— IBM

Servers where the Handler concurrently reads the request body and writes a response can encounter a data race and crash. The httputil.ReverseProxy Handler is affected.
