How to Fix CVE-2017-12862

To remediate this vulnerability, upgrade all affected Opencv python dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

opencv-python fixed: 3.3.1.11 
pip install opencv-python>=3.3.1.11
opencv-contrib-python fixed: 3.3.1.11 
pip install opencv-contrib-python>=3.3.1.11
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

pip show opencv-python

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2017-12862, inspect your installed packages using pip:

pip show opencv-python

Analyze the terminal output to locate any version of Opencv python in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.3.1.11), your application is affected.

Note: The pip show opencv-python command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-787: Out-of-bounds Write, where the product writes data past the end, or before the beginning, of the intended buffer. In Opencv python, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

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.
