Red Hat Security Advisory: OpenShift Container Platform 4.18.43 bug fix and security update

Important

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.

CWE-770 - Allocation of Resources Without Limits or Throttling

The Go standard library function net/url.Parse insufficiently validated the host/authority component and accepted some invalid URLs by effectively treating garbage before an IP-literal as ignorable. The function should have rejected this as invalid.

CWE-1286 - Improper Validation of Syntactic Correctness of Input
