Red Hat Security Advisory: OpenShift Container Platform 4.21.31 bug fix and security update

Important

A flaw was found in form-data, a library for creating readable multipart/form-data streams. A remote attacker can exploit this vulnerability by injecting carriage return (CR), line feed (LF), or double-quote (") characters into the `field` argument of `FormData#append` or the `filename` option. This allows the attacker to inject additional headers or smuggle entire additional multipart parts into requests, potentially enabling them to add or override form fields and compromise data integrity.

CWE-93 - Improper Neutralization of CRLF Sequences ('CRLF Injection')

A flaw was found in the HTTP/2 protocol implementation within the Go standard library (golang.org/x/net and net/http/internal/http2). A remote attacker can exploit this vulnerability by sending a specially crafted HTTP/2 SETTINGS frame with the SETTINGS_MAX_FRAME_SIZE parameter set to zero. This malicious frame causes the transport layer to enter an infinite loop of writing CONTINUATION frames, leading to resource exhaustion and a Denial of Service (DoS) condition.

CWE-606 - Unchecked Input for Loop Condition
