Hi,
The following vulnerability was published for netty.
CVE-2023-34462[0]:
| Netty is an asynchronous event-driven network application framework
| for rapid development of maintainable high performance protocol
| servers & clients. The `SniHandler` can allocate up to 16MB of heap
| for each channel during the TLS handshake. When the handler or the
| channel does not have an idle timeout, it can be used to make a TCP
| server using the `SniHandler` to allocate 16MB of heap. The
| `SniHandler` class is a handler that waits for the TLS handshake to
| configure a `SslHandler` according to the indicated server name by
| the `ClientHello` record. For this matter it allocates a `ByteBuf`
| using the value defined in the `ClientHello` record. Normally the
| value of the packet should be smaller than the handshake packet but
| there are not checks done here and the way the code is written, it
| is possible to craft a packet that makes the
| `SslClientHelloHandler`. This vulnerability has been fixed in
| version 4.1.94.Final.
