Summary

CVE-2024-23325 is a vulnerability affecting Envoy, a high-performance edge/middle/service proxy. This issue arises when Envoy encounters an unsupported address type in Proxy protocol, causing a crash. Notably, this vulnerability occurs on hosts with IPv6 disabled and a listener config with proxy protocol enabled. Even if the entire communication chain uses IPv4, a client can still present an IPv6 address to the target server, triggering the crash. Users are strongly advised to upgrade to Envoy versions 1.29.1, 1.28.1, 1.27.3, or 1.26.7 to address this vulnerability. No known workarounds are available.
