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
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 https://github.com/envoyproxy/envoy/security/advisories/GHSA-m4j9-86g3-8f49 https://access.redhat.com/security/cve/CVE-2022-29224 https://bugzilla.redhat.com/show_bug.cgi?id=2088738 • CWE-476: NULL Pointer Dereference •
CVSS: 7.5EPSS: 0%CPEs: 4EXPL: 0CVE-2021-43826 – Crash when tunneling TCP over HTTP in Envoy
https://notcve.org/view.php?id=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 <envoy_v3_api_field_extensions.filters.network.tcp_proxy.v3.TcpProxy.tunneling_config>` and the downstream connection disconnects while the the upstream connection or http/2 stream is still being established. There are no workarounds for this issue. Users are advised to upgrade.

CVSS: 7.5EPSS: 0%CPEs: 4EXPL: 0CVE-2021-43825 – Use-after-free in Envoy
https://notcve.org/view.php?id=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 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 memory block. If this happens Envoy will crash resulting in a denial of service. • https://github.com/envoyproxy/envoy/commit/148de954ed3585d8b4298b424aa24916d0de6136 https://github.com/envoyproxy/envoy/security/advisories/GHSA-h69p-g6xg-mhhh https://access.redhat.com/security/cve/CVE-2021-43825 https://bugzilla.redhat.com/show_bug.cgi?id=2050746 • 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
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.

CVSS: 9.8EPSS: 0%CPEs: 4EXPL: 0CVE-2022-21654 – Incorrect configuration handling allows TLS session re-use without re-validation in Envoy
https://notcve.org/view.php?id=CVE-2022-21654
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 to upgrade.
