Red Hat Security Advisory: Red Hat Advanced Cluster Management for Kubernetes v2.16.2 security update

Important

A flaw was found in Apache Thrift c_glib language bindings. A remote attacker could send specially crafted requests to a c_glib-based Thrift server, leading to a mismatched memory management routines vulnerability. This could cause the server to crash with a "free(): invalid pointer" error, resulting in a Denial of Service (DoS).

CWE-763 - Release of Invalid Pointer or Reference

A flaw was found in fast-uri. A remote attacker could exploit this vulnerability by crafting a malicious Uniform Resource Identifier (URI) that contains percent-encoded authority delimiters. The fast-uri library incorrectly decodes these delimiters during normalization and then re-emits them as raw separators, which can change the URI's intended authority. This issue allows applications that perform host allowlist checks, redirect validation, or outbound request routing to be steered to a different authority than specified, potentially bypassing security controls.

CWE-140 - Improper Neutralization of Delimiters

A flaw was found in github.com/jackc/pgx. This memory-safety vulnerability could potentially lead to unexpected behavior or system instability.

CWE-787 - Out-of-bounds Write

A flaw was found in github.com/jackc/pgx, a PostgreSQL driver for Go. This memory-safety vulnerability could allow an attacker to cause various impacts, such as denial of service (DoS) or potentially arbitrary code execution, by exploiting memory corruption issues. The exact method of exploitation and specific consequences would depend on the nature of the memory corruption.

CWE-787 - Out-of-bounds Write

A flaw was found in follow-redirects. When an HTTP request follows a cross-domain redirect (a redirection to a different domain), custom authentication headers, such as X-API-Key or X-Auth-Token, are not properly stripped. This allows these sensitive headers to be forwarded verbatim to the redirect target, potentially leading to the unintended disclosure of authentication information to an untrusted third party.

CWE-212 - Improper Removal of Sensitive Information Before Storage or Transfer

A flaw was found in the Apache Thrift TFramedTransport Go language implementation. This integer overflow or wraparound vulnerability could potentially allow an attacker to cause unexpected behavior or resource exhaustion, leading to a denial of service.

CWE-190 - Integer Overflow or Wraparound
