Red Hat Security Advisory: OpenShift Container Platform 4.16.65 bug fix and security update

Important

A flaw was found in gRPC-Go, the Go language implementation of gRPC. This vulnerability, an authorization bypass, is caused by improper input validation of the HTTP/2 `:path` pseudo-header. A remote attacker can exploit this by sending raw HTTP/2 frames with a malformed `:path` that omits the mandatory leading slash. This allows the attacker to bypass defined security policies, potentially leading to unauthorized access to services or information disclosure.

CWE-551 - Incorrect Behavior Order: Authorization Before Parsing and Canonicalization

A flaw was found in serialize-javascript. An attacker can exploit this vulnerability by providing a specially crafted "array-like" object with an excessively large length property during the serialization process. This action causes the application to enter an intensive loop, leading to 100% CPU consumption and an indefinite hang. The primary consequence is a Denial of Service (DoS), making the affected system unresponsive.

CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')
