fix: the path buffer allocation at env in env.h

[orbisai0security]

Summary

Fix high severity security issue in ocean/impulse_wars/env.h.

Vulnerability

Field	Value
ID	V-002
Severity	HIGH
Scanner	multi_agent_ai
Rule	V-002
File	ocean/impulse_wars/env.h:590
CWE	CWE-120

Description: The path buffer allocation at env.h:590 computes its size as map->rows * map->columns * map->rows * map->columns * sizeof(uint8_t). When map dimensions are stored in 32-bit integers, this four-way multiplication overflows for moderate map sizes (e.g., rows=256, columns=256 produces 4,294,967,296, which wraps to 0 in a 32-bit unsigned context). fastMalloc then allocates a zero-byte or tiny buffer, and subsequent path-finding writes far beyond it, causing a heap buffer overflow.

Changes

• ocean/impulse_wars/env.h

Verification
