Envoy Trust Management Issue Vulnerability (CNVD-2022-16290)

Envoy is an open source distributed proxy server. Envoy has a trust management issue vulnerability that stems from a type confusion error in the defaultvalidator.cc implementation used to implement the default certificate validation routines when handling subjectAltNames. no details of the...

Envoy Resource Management Error Vulnerability (CNVD-2022-82669)

Envoy is an open source distributed proxy server. Envoy is vulnerable to a resource management error, which stems from improper management of system resources by a networked system or product and can be exploited by an attacker to cause a denial of service...

CVE-2022-21657

A flaw was found in envoy. This issue occurs when it does not restrict the set of certificates it accepts from the peer, either as a TLS client or a TLS server, and only to those certificates that contain the necessary extendedKeyUsage id-kp-serverAuth and id-kp-clientAuth, respectively...

CVE-2022-21656

A flaw was found in envoy. The defaultvalidator.cc implementation used to implement the default certificate validation routines has a "type confusion" bug when processing subjectAltNames...

CVE-2022-21655

A flaw was found in envoy. Due to incorrect handling of the common router, a segfault is possible when internal redirects are routes with a direct response entry...

CVE-2022-21654

A flaw was found in envoy. When certificate validation settings are changed, incorrect configuration handling allows TLS session reuse without revalidation...

CVE-2021-43826

A flaw was found in envoy. If a downstream source disconnects during upstream connection establishment when tunneling TCP over HTTP, a use-after-free can occur, resulting in a denial of service...

CVE-2021-43824

A flaw was found in envoy. A crafted request can potentially trigger a NULL pointer dereference when using a WT filter saferegex match...

CVE-2021-43825

A flaw was found in envoy. If the amount of buffered data by envoy goes over the limit, the buffer may overflow while a response is being processed by the filter chain. This issue possibly causes the operation to abort incorrectly, resulting in the access of a freed memory block...

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...

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...

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-2022-21657

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

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...

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-2021-43826

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...

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...
