CVE-2022-21656

Envoy is an open source edge and service proxy, designed for cloud-native applications. The defaultvalidator.cc implementation used to implement the default certificate validation routines has a "type confusion" bug when processing subjectAltNames. This processing allows, for example, an rfc822Na...

CVE-2021-43824

Envoy is an open source edge and service proxy, designed for cloud-native applications. In affected versions a crafted request crashes Envoy when a CONNECT request is sent to JWT filter configured with regex match. This provides a denial of service attack vector. The only workaround is to not use...

CVE-2021-43825

Envoy is an open source edge and service proxy, designed for cloud-native applications. Sending a locally generated response must stop further processing of request or response data. Envoy tracks the amount of buffered request and response data and aborts the request if the amount of buffered dat...

CVE-2021-43826

Envoy is an open source edge and service proxy, designed for cloud-native applications. In affected versions of Envoy a crash occurs when configured for :ref:upstream tunneling and the downstream connection disconnects while the the upstream connection or http/2 stream is still being established...

This processing allows, for example, an rfc822Na...

CVE-2021-43825

CVE-2021-43825 is a vulnerability in Envoy where a buffer overflow during response processing in the filter chain may cause a use-after-free, potentially crashing the process and causing a denial of service. The provided connected documents (OSV, RHSA/Nessus listings) describe the issue as a use-...

CVE-2022-21654 Incorrect configuration handling allows TLS session re-use without re-validation in Envoy

Envoy is an open source edge and service proxy, designed for cloud-native applications. Envoy's tls allows re-use when some cert validation settings have changed from their default configuration. The only workaround for this issue is to ensure that default tls settings are used. Users are advised...

CVE-2022-21657 X.509 Extended Key Usage and Trust Purposes bypass in Envoy

Envoy is an open source edge and service proxy, designed for cloud-native applications. In affected versions Envoy does not restrict the set of certificates it accepts from the peer, either as a TLS client or a TLS server, to only those certificates that contain the necessary extendedKeyUsage...

CVE-2022-23606

CVE-2022-23606 affects Envoy. When a cluster is deleted via Cluster Discovery Service (CDS), idle connections to endpoints in that cluster are disconnected. A recursion was introduced in the disconnect procedure, which can lead to stack exhaustion and abnormal process termination when many idle c...
