    Memory Allocation with Excessive Size Value

    Affected versions of this package are vulnerable to Memory Allocation with Excessive Size Value through the decodeHuffmanEncodedLiteral function in the QPACK decoder, which allocates memory for a byte array based on a length value received from the network without verifying that sufficient data is present. An attacker can cause excessive memory allocation, leading to server slowdown, stalling, or crashing by sending specially crafted HTTP/3 HEADERS frames with malicious QPACK sections.

    How to fix Memory Allocation with Excessive Size Value?

    Upgrade io.netty:netty-codec-http3 to version 4.2.13.Final or higher.
