Affected packages

• PyPI opencv-python: < 3.3.1.11 → fixed in 3.3.1.11 • PyPI opencv-contrib-python: < 3.3.1.11 → fixed in 3.3.1.11

Description

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.
