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...

Code injection

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...

Design/Logic Flaw

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...

Design/Logic Flaw

Envoy is an open source edge and service proxy, designed for cloud-native applications. The envoy common router will segfault if an internal redirect selects a route configured with direct response or redirect actions. This will result in a denial of service. As a workaround turn off internal...

Buffer overflow

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...

Design/Logic Flaw

Envoy is an open source edge and service proxy, designed for cloud-native applications. When a cluster is deleted via Cluster Discovery Service CDS all idle connections established to endpoints in that cluster are disconnected. A recursion was introduced in the procedure of disconnecting idle...

Type confusion

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...

Code injection

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...

Default configuration

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-2021-43826 Crash when tunneling TCP over HTTP in Envoy

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...

CVE-2021-43826

CVE-2021-43826 affects Envoy: a crash occurs in affected versions when tunneling TCP over HTTP is used and the downstream connection disconnects while the upstream connection or HTTP/2 stream is still establishing. This is a crash (not a memory corruption) with availability impact; no public expl...

CVE-2021-43825 Use-after-free in Envoy

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-2021-43825

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-2021-43825 Use-after-free in Envoy

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-2022-21655

CVE-2022-21655 affects Envoy’s common router: if an internal redirect selects a route configured with direct response or redirect actions, it can segfault, causing a denial of service. The available sources confirm this behavior and provide a workaround: disable internal redirects on listeners wh...

CVE-2022-21655 Incorrect handling of internal redirects results in crash in Envoy

Envoy is an open source edge and service proxy, designed for cloud-native applications. The envoy common router will segfault if an internal redirect selects a route configured with direct response or redirect actions. This will result in a denial of service. As a workaround turn off internal...

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...
