Overview
Affected versions of this package are vulnerable to Memory Allocation with Excessive Size Value via the parsing process of HTTP/3 frames and improper enforcement of QPACK decompression limits. An attacker can cause excessive memory allocation by sending specially crafted HTTP/3 or HEADERS frames with manipulated length fields or QPACK payloads, leading to resource exhaustion and service disruption.
