Improper Restriction of Operations within the Bounds of a Memory Buffer in OpenCV
Quick fix
PYSEC-2026-699 — opencv-contrib-python: upgrade to the fixed version with the command below.
pip install --upgrade 'opencv-contrib-python>=3.3.1.11'Details
In modules/imgcodecs/src/grfmt_pxm.cpp, the length of buffer AutoBuffer _src is small than expected, which will cause copy buffer overflow later. If the image is from remote, may lead to remote code execution or denial of service. This affects OpenCV 3.3 (corresponding to OpenCV-Python 3.3.0.9) and earlier.
