nifti_clib through 3.0.1 contains a stack-based out-of-bounds read and write vulnerability in nifti_convert_n2hdr2nim() because the NIfTI-2 dim[0] value is never range-checked. Attackers can supply a crafted 540-byte NIfTI-2 header read via nifti_image_read() to crash applications or corrupt stack memory.
