Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Jetty's jetty-server package, versions 10.0.0 before 10.0.10 and 11.0.0 before 11.0.10, does not release pooled ByteBuffers on some SslConnection error paths. A remote client that sends an expired certificate during a TLS handshake requiring client authentication can cause these buffers to leak, which can lead to memory exhaustion. Upgrade to 10.0.10 or 11.0.10. As a workaround, configure a RetainableByteBufferPool with a maximum heap and direct memory limit to cap the leaked memory.
