SCA: security update for github.com/cilium/cilium (GHSA-r5x6-w42p-jhpp)

critical Tenable Self-Hosted Container Security Plugin ID 418515

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. In version
 1.13.0, when Cilium is started, there is a short period when Cilium eBPF programs are not attached to the
 host. During this period, the host does not implement any of Cilium's featureset. This can cause
 disruption to newly established connections during this period due to the lack of Load Balancing, or can
 cause Network Policy bypass due to the lack of Network Policy enforcement during the window. This
 vulnerability impacts any Cilium-managed endpoints on the node (such as Kubernetes Pods), as well as the
 host network namespace (including Host Firewall). This vulnerability is fixed in Cilium 1.13.1 or later.
 Cilium releases 1.12.x, 1.11.x, and earlier are not affected. There are no known workarounds.
 (CVE-2023-27595)
