  "details": "CFITSIO through 4.7.0 contains a heap-based out-of-bounds read\nvulnerability in the imcompress.c unquantize helpers that allows\nattackers to read memory before the fits_rand_value table via a zero or\nnegative ZDITHER0 seed. Attackers can supply a crafted FITS file with a\nSUBTRACTIVE_DITHER_1 compressed image, read through fits_open_file() and\nfits_read_pix(), to cause crashes or leak heap contents in decoded\npixels.\n",
