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: 1CVE-2024-32974 – Envoy affected by a crash in EnvoyQuicServerStream::OnInitialHeadersComplete()
https://notcve.org/view.php?id=CVE-2024-32974
Envoy is a cloud-native, open source edge and service proxy. A crash was observed in `EnvoyQuicServerStream::OnInitialHeadersComplete()` with following call stack. It is a use-after-free caused by QUICHE continuing push request headers after `StopReading()` being called on the stream. As after `StopReading()`, the HCM's `ActiveStream` might have already be destroyed and any up calls from QUICHE could potentially cause use after free.

https://notcve.org/view.php?id=CVE-2024-32975
Envoy is a cloud-native, open source edge and service proxy. There is a crash at `QuicheDataReader::PeekVarInt62Length()`. It is caused by integer underflow in the `QuicStreamSequencerBuffer::PeekRegion()` implementation. Envoy es un proxy de servicio y borde de código abierto, nativo de la nube.

https://notcve.org/view.php?id=CVE-2024-34362
Envoy is a cloud-native, open source edge and service proxy. There is a use-after-free in `HttpConnectionManager` (HCM) with `EnvoyQuicServerStream` that can crash Envoy. An attacker can exploit this vulnerability by sending a request without `FIN`, then a `RESET_STREAM` frame, and then after receiving the response, closing the connection.

https://notcve.org/view.php?id=CVE-2024-34364
Envoy is a cloud-native, open source edge and service proxy. Envoy exposed an out-of-memory (OOM) vector from the mirror response, since async HTTP client will buffer the response with an unbounded buffer. Envoy es un proxy de servicio y borde de código abierto, nativo de la nube. Envoy expuso un vector de falta de memoria (OOM) de la respuesta reflejada, ya que el cliente HTTP asíncrono almacenará la respuesta en un búfer ilimitado. • https://github.com/envoyproxy/envoy/security/advisories/GHSA-xcj3-h7vf-fw26 • CWE-400: Uncontrolled Resource Consumption CWE-787: Out-of-bounds Write •
