Affected: Bitnami: envoy

Envoy is an open source L7 proxy and communication bus designed for large modern service oriented architectures. Versions 1.34.0 through 1.34.4 and 1.35.0 contain a use-after-free (UAF) vulnerability in the DNS cache, causing abnormal process termination. The vulnerability is in Envoy's Dynamic Forward Proxy implementation, occurring when a completion callback for a DNS resolution triggers new DNS resolutions or removes existing pending resolutions. This condition may occur when the following conditions are met: dynamic Forwarding Filter is enabled, the `envoy.reloadable_features.dfp_cluster_resolves_hosts` runtime flag is enabled, and the Host header is modified between the Dynamic Forwarding Filter and Router filters. This issue is resolved in versions 1.34.5 and 1.35.1. To work around this issue, set the envoy.reloadable_features.dfp_cluster_resolves_hosts runtime flag to false.

Affected: Go: github.com/envoyproxy/envoy

### Summary

A use-after-free (UAF) vulnerability in Envoy's DNS cache causes abnormal process termination. Envoy may reallocate memory when processing a pending DNS resolution, causing list iterator to reference freed memory.

### Details

The vulnerability exists in Envoy's Dynamic Forward Proxy implementation starting from version v1.34.0. The issue occurs when a completion callback for a DNS resolution triggers new DNS resolutions or removes existing pending resolutions. This condition may occur in the following configuration:

1. Dynamic Forwarding Filter is enabled. 2. `envoy.reloadable_features.dfp_cluster_resolves_hosts` runtime flag is enabled. 3. The Host header is modified between the Dynamic Forwarding Filter and Router filters.

### Impact

Denial of service due to abnormal process termination.

### Attack vector(s) Request to Envoy configured as indicated above.

### Patches Users should upgrade to v1.35.1 or v1.34.5.

### Workaround Set the `envoy.reloadable_features.dfp_cluster_resolves_hosts` runtime flag to `false`.

### Detection Abnormal process termination with the `Envoy::Event::DispatcherImpl::runPostCallbacks()` frame in the call stack.
