Descriptions
The net/url package does not set a limit on the number of query parameters in a query. While the maximum size of query parameters in URLs is generally limited by the maximum request header size, the net/http.Request.ParseForm method can parse large URL-encoded forms. Parsing a large form containing many unique query parameters can cause excessive memory consumption.
An update for the go-toolset:rhel8 module is now available for Red Hat Enterprise Linux 8. Issues addressed include a memory exhaustion vulnerability.
