Linkerd - stable-2.14.2

stable-2.14.2

This stable release fixes issues in the proxy and Destination controller which
can result in Linkerd proxies sending traffic to stale endpoints. In addition,
it contains a bug fix for profile resolutions for pods bound on host ports and
includes patches for security advisory CVE-2023-44487/GHSA-qppj-fm5r-hxr3

• Control Plane
• Fixed an issue where the Destination controller could stop processing
  changes in the endpoints of a destination, if a proxy subscribed to that
  destination stops reading service discovery updates. This issue results in
  proxies attempting to send traffic for that destination to stale endpoints
  (#11491, fixes #11480, #11279, #10590)
• Fixed an issue where the Destination controller would not update pod
  metadata for profile resolutions for a pod accessed via the host network
  (e.g. HostPort endpoints) (#11334)

• Addressed CVE-2023-44487/GHSA-qppj-fm5r-hxr3 by upgrading several
  dependencies (including Go's gRPC and net libraries)

• Proxy

• Fixed a regression where the proxy rendered grpc_status metric labels as
  a string rather than as the numeric status code (linkerd2-proxy#2480;
  fixes #11449)
• Fixed a regression introduced in stable-2.13.0 where proxies would not
  terminate unused service discovery watches, exerting backpressure on the
  Destination controller, potentially causing it to become
  stuck (linkerd2-proxy#2484)
