How to Fix CVE-2017-17760

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: 3.4.0.12 
pip install opencv-python>=3.4.0.12
opencv-contrib-python fixed: 3.4.0.12 
pip install opencv-contrib-python>=3.4.0.12
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-2017-17760, 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 3.4.0.12), 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-119: Improper Restriction of Operations within the Bounds of a Memory Buffer, where the product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. this may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data. 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

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.
