A host is considered authorized if it matches at least one Subject Alternative Name (SAN) in one of the certificates installed on your load balancers.What to do Some of your users may experience an HTTP 401 Unauthorized response with an IAP error code 52 while trying to access apps or services. This error code means that the client sent a Host header which does not match any Subject Alternative Names associated with the load balancer's SSL certificate(s).

The Envoy project recently discovered a set of vulnerabilities. All issues listed below are fixed in Envoy release 1.21.1. CVE-2022-23606: When a cluster is deleted via Cluster Discovery Service (CDS) all idle connections established to endpoints in that cluster are disconnected. A recursion was erroneously introduced in Envoy version 1.19 to 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. CVE-2022-21655: Envoy's internal redirect code assumes that a route entry exists. When an internal redirect is done to a route which has a direct response entry and no route entry, it results in dereferencing a null pointer and crashing. CVE-2021-43826: When Envoy is configured to use tcp_proxy which uses upstream tunneling (over HTTP), and downstream TLS termination, Envoy will crash if the downstream client disconnects during the TLS handshake while the upstream HTTP stream is still being established. The downstream disconnect can be either client or server initiated. The client can disconnect for any reason. The server may disconnect if, for example, it has no TLS ciphers or TLS protocol versions compatible with the client. It may be possible to trigger this crash in other downstream configurations as well. CVE-2021-43825: 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 locally generated response is sent because of the internal 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. CVE-2021-43824: Envoy crashes when using the JWT filter with a "safe_regex" match rule and a specially crafted request like "CONNECT host:port HTTP/1.1". When reaching the JWT filter, a "safe_regex" rule should evaluate the URL path but there is none here, and Envoy crashes with segfaults. CVE-2022-21654: Envoy would incorrectly allow TLS session resumption after mTLS validation settings had been reconfigured. If a client certificate was allowed with the old configuration but disallowed with the new configuration, the client could resume the previous TLS session even though the current configuration should disallow it. Changes to the following settings are affected: match_subject_alt_names CRL changes allow_expired_certificate Trust_chain_verification only_verify_leaf_cert_crl CVE-2022-21657: Envoy does not restrict the set of certificates it accepts from the peer, either as a TLS client or a TLS ser		 Guideline ★★★
