Early versions of `amphp/http-client` with HTTP/2 support (v4.0.0-rc10 to 4.0.0) will collect HTTP/2 `CONTINUATION` frames in an unbounded buffer and will not check the header size limit until it has received the `END_HEADERS` flag, resulting in an OOM crash. Later versions of `amphp/http-client` (v4.1.0-rc1 and up) depend on `amphp/http` for HTTP/2 processing and will therefore need an updated version of `amphp/http`, see [GHSA-qjfw-cvjf-f4fm](https://github.com/amphp/http/security/advisories/GHSA-qjfw-cvjf-f4fm). ## Acknowledgements Thank you to [Bartek Nowotarski](https://nowotarski.info/) for reporting the vulnerability.

`amphp/http` will collect HTTP/2 `CONTINUATION` frames in an unbounded buffer and will not check the header size limit until it has received the `END_HEADERS` flag, resulting in an OOM crash. `amphp/http-client` and `amphp/http-server` are indirectly affected if they're used with an unpatched version of `amphp/http`. Early versions of `amphp/http-client` with HTTP/2 support (v4.0.0-rc10 to 4.0.0) are also directly affected. ## Acknowledgements Thank you to [Bartek Nowotarski](https://nowotarski.info/) for reporting the vulnerability.

A NULL pointer dereference flaw was found in KubeVirt. This flaw allows an attacker who has access to a virtual machine guest on a node with DownwardMetrics enabled to cause a denial of service by issuing a high number of calls to vm-dump-metrics --virtio and then deleting the virtual machine.

### Impact The 19.0.0 release of Wasmtime contains a regression introduced during its development which can lead to a guest WebAssembly module causing a panic in the host runtime. A valid WebAssembly module, when executed at runtime, may cause this panic. The panic in question is caused when a WebAssembly module issues a `table.*` instruction which uses a dropped element segment with a table that also has an `externref` type. This causes Wasmtime to erroneously use an empty function segment instead of an empty externref segment to perform this operation. This mismatch in types causes a panic in Wasmtime when it's asserted that an externref table is only viewed as externrefs. This regression was introduced during the development of the 19.0.0 release and only affects the 19.0.0 release. This panic requires the `reference-types` WebAssembly feature to be enabled, and it is enabled by default. Toolchains are not known to generate this pattern by default so it's likely a module would nee...
