Improper Restriction of Operations within the Bounds of a Memory Buffer in OpenCV

Source: GitHub Advisory Database (reviewed) High CVE-2017-12862

Packages

Details

As written in the advisory (Markdown source, shown as plain text).

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.
