### Impact `SslConnection` does not release `ByteBuffer`s in case of error code paths. For example, TLS handshakes that require client-auth with clients that send expired certificates will trigger a TLS handshake errors and the `ByteBuffer`s used to process the TLS handshake will be leaked. ### Workarounds Configure explicitly a `RetainableByteBufferPool` with `max[Heap|Direct]Memory` to limit the amount of memory that is leaked. Eventually the pool will be full of "active" entries (the leaked ones) and will provide `ByteBuffer`s that will be GCed normally. _With embedded-jetty_ ``` java int maxBucketSize = 1000; long maxHeapMemory = 128 * 1024L * 1024L; // 128 MB long maxDirectMemory = 128 * 1024L * 1024L; // 128 MB RetainableByteBufferPool rbbp = new ArrayRetainableByteBufferPool(0, -1, -1, maxBucketSize, maxHeapMemory, maxDirectMemory); server.addBean(rbbp); // make sure the ArrayRetainableByteBufferPool is added before the server is started server.start(); ``` _With jetty-home...

Hyperledger Fabric is a permissioned distributed ledger framework. In affected versions if a consensus client sends a malformed consensus request to an orderer it may crash the orderer node. A fix has been added in commit 0f1835949 which checks for missing consensus messages and returns an error to the consensus client should the message be missing. Users are advised to upgrade to versions 2.2.7 or v2.4.5. There are no known workarounds for this issue.
