  "details": "Imager versions before 1.032 for Perl have a heap out-of-bounds read in the bundled Imager::File::SGI reader via a 16-bit RLE literal run in read_rgb_16_rle.  read_rgb_16_rle guards each literal run with if (count \u003e data_left), but count is a pixel count while every 16-bit sample consumes two bytes. The copy loop reads inp[0] * 256 + inp[1] and advances two bytes per pixel, so a run with data_left / 2 \u003c count \u003c= data_left passes the guard yet consumes 2 * count bytes and reads past the end of the buffer. The 8-bit path is unaffected because there one pixel is one byte.  Reading a crafted SGI image through Imager-\u003eread triggers the over-read before the parser rejects the malformed image, which can crash the process.",
