SCA: security update for github.com/cilium/cilium (GHSA-gj2r-phwg-6rww)

critical Tenable Cloud Security Plugin ID 415160

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. An attacker
 with the ability to update pod labels can cause Cilium to apply incorrect network policies. This issue
 arises due to the fact that on pod update, Cilium incorrectly uses user-provided pod labels to select the
 policies which apply to the workload in question. This can affect Cilium network policies that use the
 namespace, service account or cluster constructs to restrict traffic, Cilium clusterwide network policies
 that use Cilium namespace labels to select the Pod and Kubernetes network policies. Non-existent construct
 names can be provided, which bypass all network policies applicable to the construct. For example,
 providing a pod with a non-existent namespace as the value of the `io.kubernetes.pod.namespace` label
 results in none of the namespaced CiliumNetworkPolicies applying to the pod in question. This attack
 requires the attacker to have Kubernetes API Server access, as described in the Cilium Threat Model. This
 issue has been resolved in: Cilium versions 1.14.2, 1.13.7, and 1.12.14. Users are advised to upgrade. As
 a workaround an admission webhook can be used to prevent pod label updates to the
 `k8s:io.kubernetes.pod.namespace` and `io.cilium.k8s.policy.*` keys. (CVE-2023-39347)
