• CVE-2021-39162HigSep 9, 2021
  affected < 1.18.4fixed 1.18.4

  Pomerium is an open source identity-aware access proxy. Envoy, which Pomerium is based on, can abnormally terminate if an H/2 GOAWAY and SETTINGS frame are received in the same IO event. This can lead to a DoS in the presence of untrusted *upstream* servers. 0.15.1 contains an up

  affected >= 1.16.0, < 1.16.5fixed 1.16.5

  Envoy is an open source L7 proxy and communication bus designed for large modern service oriented architectures. In affected versions envoy’s procedure for resetting a HTTP/2 stream has O(N^2) complexity, leading to high CPU utilization when a large number of streams are reset. D

• CVE-2021-32777HigAug 24, 2021
  affected >= 1.16.0, < 1.16.5fixed 1.16.5

• CVE-2021-29492HigMay 28, 2021
  affected < 1.15.5fixed 1.15.5

  Envoy is a cloud-native edge/middle/service proxy. Envoy does not decode escaped slash sequences `%2F` and `%5C` in HTTP URL paths in versions 1.18.2 and before. A remote attacker may craft a path with escaped slashes, e.g. `/something%2F..%2Fadmin`, to bypass access control, e.g

• CVE-2021-29258HigMay 20, 2021
  affected >= 1.14.6, < 1.14.7fixed 1.14.7

  An issue was discovered in Envoy 1.14.0. There is a remotely exploitable crash for HTTP2 Metadata, because an empty METADATA map triggers a Reachable Assertion.

• CVE-2021-28683HigMay 20, 2021
  affected >= 1.16.2, < 1.16.3fixed 1.16.3

  An issue was discovered in Envoy through 1.71.1. There is a remotely exploitable NULL pointer dereference and crash in TLS when an unknown TLS alert code is received.

• CVE-2021-28682HigMay 20, 2021
  affected >= 1.14.6, < 1.14.7fixed 1.14.7

  An issue was discovered in Envoy through 1.71.1. There is a remotely exploitable integer overflow in which a very large grpc-timeout value leads to unexpected timeout calculations.

• CVE-2021-21378HigMar 11, 2021
  affected >= 1.17.0, < 1.17.1fixed 1.17.1

  Envoy is a cloud-native high-performance edge/middle/service proxy. In Envoy version 1.17.0 an attacker can bypass authentication by presenting a JWT token with an issuer that is not in the provider list when Envoy's JWT Authentication filter is configured with the `allow_missing

• CVE-2020-35471HigDec 15, 2020
  affected < 1.16.1fixed 1.16.1

  Envoy before 1.16.1 mishandles dropped and truncated datagrams, as demonstrated by a segmentation fault for a UDP packet size larger than 1500.

• CVE-2020-35470HigDec 15, 2020
  affected < 1.16.1fixed 1.16.1

  Envoy before 1.16.1 logs an incorrect downstream address because it considers only the directly connected peer, not the information in the proxy protocol header. This affects situations with tcp-proxy as the network filter (not HTTP filters).

• CVE-2020-25017HigOct 1, 2020
  affected < 1.12.7fixed 1.12.7

  Envoy through 1.15.0 only considers the first value when multiple header values are present for some HTTP headers. Envoy’s setCopy() header map API does not replace all existing occurences of a non-inline header.

• CVE-2020-15104MedJul 14, 2020
  affected < 1.12.6fixed 1.12.6

  In Envoy before versions 1.12.6, 1.13.4, 1.14.4, and 1.15.0 when validating TLS certificates, Envoy would incorrectly allow a wildcard DNS Subject Alternative Name apply to multiple subdomains. For example, with a SAN of *.example.com, Envoy would incorrectly allow nested.subdoma
