fix: Resolve architectural vulnerabilities and resource leaks in VisionClaw OS#1
fix: Resolve architectural vulnerabilities and resource leaks in VisionClaw OS#1
Conversation
…onClaw OS - Subprocess Thread-Safety: Added 30s timeout and exception handling to isolated UI overlay `subprocess.run` to prevent orchestrator hangs (`agent_os/ui_overlay.py`). - Null Pointer Failures: Added explicit key checks and `.get()` defaults for coordinate resolution logic (`orchestration/orchestrator.py`). - Security Vulnerabilities: Enhanced blocklists in `tools/os_controller.py` with more shell patterns, blocked nested `osascript -e`, and `do shell script`. Hardened `SemanticGuardrail` in `orchestration/semantic_guard.py` with additional destructive intent patterns. - RAM Leaks: Added a `threading.Lock()` to the `AmbientPerceptionBuffer` and explicitly closed PIL Image objects (`img.close()`) when frames age out or the service stops to prevent memory buildup (`agent_os/ambient_buffer.py`). - Disk Space Leaks: Refactored `SetOfMarkVisionFallback` and `GridOverlay` to use `tempfile.mkstemp()`. To prevent gigabytes of leaks over long sessions, explicitly added `os.remove()` in `UnifiedUICore.generate_vision_grid` right after Base64 encoding.
