CVSS: 7.5EPSS: 0%CPEs: 4EXPL: 0CVE-2024-45810 – Envoy crashes for LocalReply in http async client
https://notcve.org/view.php?id=CVE-2024-45810
Envoy is a cloud-native high-performance edge/middle/service proxy. Envoy will crash when the http async client is handling `sendLocalReply` under some circumstance, e.g., websocket upgrade, and requests mirroring. The http async client will crash during the `sendLocalReply()` in http async client, one reason is http async client is duplicating the status code, another one is the destroy of router is called at the destructor of the async stream, while the stream is deferred deleted at first. There will be problems that the stream decoder is destroyed but its reference is called in `router.onDestroy()`, causing segment fault. This will impact ext_authz if the `upgrade` and `connection` header are allowed, and request mirrorring. • https://github.com/envoyproxy/envoy/security/advisories/GHSA-qm74-x36m-555q https://access.redhat.com/security/cve/CVE-2024-45810 https://bugzilla.redhat.com/show_bug.cgi?id=2313687 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVSS: 7.5EPSS: 0%CPEs: 4EXPL: 0CVE-2024-32475 – Envoy RELEASE_ASSERT using auto_sni with :authority header > 255 bytes
https://notcve.org/view.php?id=CVE-2024-32475
Envoy is a cloud-native, open source edge and service proxy. When an upstream TLS cluster is used with `auto_sni` enabled, a request containing a `host`/`:authority` header longer than 255 characters triggers an abnormal termination of Envoy process. Envoy does not gracefully handle an error when setting SNI for outbound TLS connection. The error can occur when Envoy attempts to use the `host`/`:authority` header value longer than 255 characters as SNI for outbound TLS connection. SNI length is limited to 255 characters per the standard. • https://github.com/envoyproxy/envoy/commit/b47fc6648d7c2dfe0093a601d44cb704b7bad382 https://github.com/envoyproxy/envoy/security/advisories/GHSA-3mh5-6q8v-25wj https://access.redhat.com/security/cve/CVE-2024-32475 https://bugzilla.redhat.com/show_bug.cgi?id=2276149 • CWE-253: Incorrect Check of Function Return Value CWE-617: Reachable Assertion •
