What it is

MOOS-IvP through 24.8.1 contains a denial of service vulnerability in the Demuxer::addMuxPacket() function that trusts the packet count declared in mux headers without validation. Attackers can declare arbitrarily large packet counts to trigger unbounded memory allocation, exhausting system resources and causing service unavailability.
