## Overview

OpenCV 3.3.1 (corresponding with opencv-python and opencv-contrib-python 3.3.1.11) has a Buffer Overflow in the cv::PxMDecoder::readData function in grfmt_pxm.cpp, because an incorrect size value is used.

## Affected packages

- `opencv-python < 3.4.0.12`
- `opencv-contrib-python < 3.4.0.12`

## Remediation

Upgrade to a patched release:

- `opencv-python 3.4.0.12`
- `opencv-contrib-python 3.4.0.12`
