Description

The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

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.
