Scanner	multi_agent_ai
Rule	V-001
File	veejay-current/veejay-core/libvjnet/packet.c:53
CWE	CWE-120

Description: The packet.c file performs multiple veejay_memcpy operations using CHUNK_SIZE and len values derived from network packet headers without validating that these sizes fit within the destination buffer boundaries. An attacker sending crafted network packets with manipulated size fields can trigger heap buffer overflows, enabling remote code execution.
