Affected: Bitnami: envoy

Envoy is a high-performance edge/middle/service proxy. Prior to 1.37.1, 1.36.5, 1.35.8, and 1.34.13, calling Utility::getAddressWithPort with a scoped IPv6 addresses causes a crash. This utility is called in the data plane from the original_src filter and the dns filter. This vulnerability is fixed in 1.37.1, 1.36.5, 1.35.8, and 1.34.13.

Affected: Go: github.com/envoyproxy/envoy

### Summary

Calling `Utility::getAddressWithPort` with a scoped IPv6 addresses causes a crash. This utility is called in the data plane from the original_src filter and the dns filter.

### Details

The crashing function is `Utility::getAddressWithPort`. The crash occurs if a string containing a scoped IPv6 address is passed to this function.

This vulnerability affects:

1. The **original src filter**: If the filter is configured and the original source is a scoped IPv6 address, it will cause a crash. 2. **DNS response address resolution**: If a DNS response contains a scoped IPv6 address, this will also trigger the crash.

### PoC

To reproduce the vulnerability:

1. **Method A (Original Src Filter):** Configure the `original src` filter in Envoy and provide a scoped IPv6 address as the original source. 2. **Method B (DNS Resolution):** Trigger a DNS resolution process within Envoy where the DNS response contains a scoped IPv6 address.

### Impact

This is a Denial of Service (DoS) vulnerability. It impacts users who have the `original src` filter configured or whose Envoy instances resolve addresses from DNS responses that may contain scoped IPv6 addresses.
