SCA: security update for github.com/cilium/cilium (GHSA-8fg8-jh2h-f2hc)

high Tenable Cloud Security Plugin ID 412626

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
 versions 1.11.15, 1.12.8, and 1.13.1, under specific conditions, Cilium may misattribute the source IP
 address of traffic to a cluster, identifying external traffic as coming from the host on which Cilium is
 running. As a consequence, network policies for that cluster might be bypassed, depending on the specific
 network policies enabled. This issue only manifests when Cilium is routing IPv6 traffic and NodePorts are
 used to route traffic to pods. IPv6 and endpoint routes are both disabled by default. The problem has been
 fixed and is available on versions 1.11.15, 1.12.8, and 1.13.1. As a workaround, disable IPv6 routing.
 (CVE-2023-27594)
