Description Pedro Sampaio 2017-08-21 14:34:42 EDT

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 and earlier.
