| summary: Excessive resource consumption in PackBits decompression in golang.org/x/image/tiff |
| description: | |
| The TIFF decoder does not place a limit on the size of PackBits-compressed data. |
| A maliciously-crafted image can exploit this to cause a small image (both in |
| terms of pixel width/height and encoded size) to make the decoder decode large |
| amounts of compressed data. |
