Darknet convolutional groups=0 SIGFPE PoC

This repository contains a benign security research PoC for a Darknet config that crashes OpenCV DNN with SIGFPE.

Files:

• control_same_size.cfg
• malicious_groups_zero.cfg
• tiny_shared.weights
• reproduce.py

Observed behavior:

• control config:
  • loads successfully
• malicious config:
  • with [convolutional] groups=0
  • cv2.dnn.readNetFromDarknet(...) terminates with signal 8

Reproduction:

python3 build_poc.py
python3 reproduce.py
