SCA: security update for github.com/cilium/cilium (GHSA-r7wr-4w5q-55m6)

medium Tenable Self-Hosted Container Security Plugin ID 418580

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Cilium is a networking, observability, and security solution with an eBPF-based dataplane. Prior to
 version 1.13.4, when Gateway API is enabled in Cilium, the absence of a check on the namespace in which a
 ReferenceGrant is created could result in Cilium unintentionally gaining visibility of secrets (including
 certificates) and services across namespaces. An attacker on an affected cluster can leverage this issue
 to use cluster secrets that should not be visible to them, or communicate with services that they should
 not have access to. Gateway API functionality is disabled by default. This vulnerability is fixed in
 Cilium release 1.13.4. As a workaround, restrict the creation of `ReferenceGrant` resources to admin users
 by using Kubernetes RBAC. (CVE-2023-34242)
