GHSA-XWX5-5C9G-X68X Ill-formed headers may lead to unexpected behavior in Istio

Impact Ill-formed headers sent to Envoy in certain configurations can lead to unexpected memory access resulting in undefined behavior or crashing. You are at most risk if you have an Istio ingress Gateway exposed to external traffic. Patches 1.12.8, 1.13.5, 1.14.1 Workarounds No. References More...

Envoy code issue vulnerability

Envoy is an open source distributed proxy server. versions prior to Envoy 1.22.1 have a code issue vulnerability that could be exploited by an attacker to crash Envoy via null pointer dereference on an upstream server controlled by the vulnerability...

Envoy has an unspecified vulnerability (CNVD-2022-82668)

Envoy is an open source distributed proxy server.A security vulnerability exists in versions of Envoy prior to 1.22.1, which stems from the fact that OAuth filters will attempt to invoke the remaining filters in the chain after issuing a local response. No detailed vulnerability details are...

Out-of-bounds Read

Istio is an open platform to connect, manage, and secure microservices. In affected versions ill-formed headers sent to Envoy in certain configurations can lead to unexpected memory access resulting in undefined behavior or crashing. Users are most likely at risk if they have an Istio ingress...

Envoy has an unspecified vulnerability (CNVD-2022-82665)

Envoy is an open source distributed proxy server. security vulnerability exists in versions prior to Envoy 1.22.1, which stems from secompressors accumulating decompressed data into an intermediate buffer before overwriting the body in decode/encodeBody, which can be exploited by attackers to...

Envoy Access Control Error Vulnerability (CNVD-2022-82666)

Envoy is an open source distributed proxy server.An access control error vulnerability exists in versions of Envoy prior to 1.22.1, which stems from allowing access in the presence of an access token for additional requests. No detailed vulnerability details are currently available...

Envoy Resource Management Error Vulnerability (CNVD-2022-82667)

Envoy is an open source distributed proxy server. versions prior to Envoy 1.22.1 are vulnerable to a resource management error, which stems from the fact that it is insecure to redirect requests with body text or trailers within Envoy, and an attacker could exploit the vulnerability to crash the...

CVE-2022-29227

A flaw was found in Envoy. Internal redirects for requests with bodies or trailers are not safe if the redirect prompts an Envoy-generated local reply. A remote attacker can exploit this to cause a denial of service. Mitigation Disable internal redirects if crashes are observed...

CVE-2022-29225

A flaw was found in Envoy. A specifically constructed HTTP body delivered by an untrusted downstream or upstream peer whose decompressed size is dramatically larger than the compressed size can be sent by an attacker to cause a denial of service. Mitigation This can be mitigated by disabling...

CVE-2022-29224

A flaw was found in Envoy. This flaw allows an attacker who controls an upstream host and also controls service discovery of that host via DNS, the EDS API, etc. to crash Envoy by forcing the removal of the host from service discovery and then failing the gRPC health check request. This issue...

CVE-2022-31045

Istio is an open platform to connect, manage, and secure microservices. In affected versions ill-formed headers sent to Envoy in certain configurations can lead to unexpected memory access resulting in undefined behavior or crashing. Users are most likely at risk if they have an Istio ingress...

CVE-2022-31045

CVE-2022-31045 affects Istio setups where ill-formed headers sent to Envoy in specific configurations can trigger undefined behavior or crashes, with risk tied to ingress gateways exposed to external traffic. Public details in connected docs indicate remediation through Istio upgrades to address ...

CVE-2022-31045 Ill-formed headers may lead to unexpected behavior in Istio

Istio is an open platform to connect, manage, and secure microservices. In affected versions ill-formed headers sent to Envoy in certain configurations can lead to unexpected memory access resulting in undefined behavior or crashing. Users are most likely at risk if they have an Istio ingress...

CVE-2022-29225

Envoy is a cloud-native high-performance proxy. In versions prior to 1.22.1 secompressors accumulate decompressed data into an intermediate buffer before overwriting the body in the decode/encodeBody. This may allow an attacker to zip bomb the decompressor by sending a small highly compressed...

CVE-2022-29227

Envoy is a cloud-native high-performance edge/middle/service proxy. In versions prior to 1.22.1 if Envoy attempts to send an internal redirect of an HTTP request consisting of more than HTTP headers, there’s a lifetime bug which can be triggered. If while replaying the request Envoy sends a local...

CVE-2022-29228

Envoy is a cloud-native high-performance proxy. In versions prior to 1.22.1 the OAuth filter would try to invoke the remaining filters in the chain after emitting a local response, which triggers an ASSERT in newer versions and corrupts memory on earlier versions. continueDecoding shouldn’t ever ...

CVE-2022-29226

Envoy is a cloud-native high-performance proxy. In versions prior to 1.22.1 the OAuth filter implementation does not include a mechanism for validating access tokens, so by design when the HMAC signed cookie is missing a full authentication flow should be triggered. However, the current...

Authentication flaw

Envoy is a cloud-native high-performance proxy. In versions prior to 1.22.1 the OAuth filter implementation does not include a mechanism for validating access tokens, so by design when the HMAC signed cookie is missing a full authentication flow should be triggered. However, the current...
