VuXML ID 7f242313-aea5-11eb-8151-67f74cf7c704

Entry 2021-05-06

The Go project reports:

http.ReadRequest can stack overflow due to recursion when given a request with a very large header (~8-10MB depending on the architecture). A http.Server which overrides the default max header of 1MB by setting Server.MaxHeaderBytes to a much larger value could also be vulnerable in the same way.
