Описание
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.
A flaw was found in the net/url package in the Go standard library. The package does not enforce a limit on the number of unique query parameters it parses. A Go application using the net/http.Request.ParseForm method will try to process all parameters provided in the request. A specially crafted HTTP request containing a massive number of query parameters will cause the application to consume an excessive amount of memory, eventually causing the application to crash or become unresponsive, resulting in a denial of service.
Отчет
To exploit this flaw, an attacker must be able to send a specially crafted HTTP request to an application parsing URL-encoded forms with net/url, specifically a request containing a large number of unique query parameters. The request will cause the application to consume an excessive amount of memory and eventually result in a denial of service, with no impact to confidentiality or integrity. Due to this reason, this vulnerability has been rated with an important severity.
Меры по смягчению последствий
Red Hat has investigated whether a possible mitigation exists for this issue, and has not been able to identify a practical example. Please update the affected package as soon as possible.
