In FreeImage 3.18.0, an out-of-bounds access occurs because of mishandling of the OpenJPEG j2k_read_ppm_v3 function in j2k.c. The value of l_N_ppm comes from the file read in, and the code does not consider that l_N_ppm may be greater than the size of p_header_data.
The product reads data past the end, or before the beginning, of the intended buffer.
