  "details": "Issue summary: When an OpenSSL QUIC server (Listener SSL object) processes\nvalid QUIC Initial packets for unknown destination connection IDs, it\ncan allocate and queue new incoming channels without enforcing any limit.\n\nImpact summary: A remote peer that can make many Initial packets reach the\nserver listener faster than the application accepts connections, can cause the\nmemory allocated to store the per-channel state to grow without any limits,\npotentially making the QUIC listener unavailable and causing Denial of Service.\n\nCWE: CWE-770: Allocation of Resources Without Limits or Throttling\n\nDescription: The function that handles inbound QUIC packets uses\nConnection-Id from the packet header to find an existing connection\n(QUIC channel). If no existing connection is found and the packet\ntype is INITIAL, the function treats the packet as a new connection. It\nallocates a new channel object and inserts it into a queue where it\nwaits to be accepted by the local application with SSL_accept(3ossl).\nThe memory occupied by these initial channel objects may grow\nwithout bounds if the application is not able to call SSL_accept()\nfrequently enough to serve these inbound connection requests.\n\nThe issue is present since OpenSSL 3.5 when the QUIC server implementation\nwas added.\n\nThe fix introduces a limit for pending connections. The default limit is set\nto 256 pending connections (waiting to be accepted by the local application).\nApplications may change the default by calling SSL_set_value_uint(3ossl).\n\nFIPS impact: no\nThe FIPS module is not affected as the QUIC implementation is outside of\nthe OpenSSL FIPS module boundary.",
