CVSS: 5.9EPSS: 0%CPEs: 1EXPL: 0CVE-2022-29224 – Segmentation fault leading to crash in Envoy
https://notcve.org/view.php?id=CVE-2022-29224
09 Jun 2022 — Envoy is a cloud-native high-performance proxy. Versions of envoy prior to 1.22.1 are subject to a segmentation fault in the GrpcHealthCheckerImpl. Envoy can perform various types of upstream health checking. One of them uses gRPC. Envoy also has a feature which can “hold” (prevent removal) upstream hosts obtained via service discovery until configured active health checking fails. • https://github.com/envoyproxy/envoy/commit/9b1c3962172a972bc0359398af6daa3790bb59db • CWE-476: NULL Pointer Dereference •

https://notcve.org/view.php?id=CVE-2021-43825
22 Feb 2022 — 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 data is over the limit by sending 413 or 500 responses. However when the buffer overflows while response is processed by the filter chain the operation may not be aborted correctly and result in accessing a freed memor... • https://github.com/envoyproxy/envoy/commit/148de954ed3585d8b4298b424aa24916d0de6136 • CWE-416: Use After Free •
CVSS: 7.5EPSS: 0%CPEs: 4EXPL: 0CVE-2022-21655 – Incorrect handling of internal redirects results in crash in Envoy
https://notcve.org/view.php?id=CVE-2022-21655
22 Feb 2022 — 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 redirects if direct response entries are configured on the same listener.

https://notcve.org/view.php?id=CVE-2022-21654
22 Feb 2022 — 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.

CVSS: 6.5EPSS: 0%CPEs: 2EXPL: 0CVE-2022-23606 – Crash when a cluster is deleted in Envoy
https://notcve.org/view.php?id=CVE-2022-23606
22 Feb 2022 — 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 connections that can lead to stack exhaustion and abnormal process termination when a cluster has a large number of idle connections. This infinite recursion causes Envoy to crash. Users are advised to upgrade. • https://github.com/envoyproxy/envoy/commit/4b6dd3b53cd5c6d4d4df378a2fc62c1707522b31 • CWE-674: Uncontrolled Recursion CWE-770: Allocation of Resources Without Limits or Throttling •

22 Feb 2022 — 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 regex in the JWT filter.
