GHSA-q675-qj96-32m9: golang.org/x/image/tiff has excessive resource consumption in PackBits decompression
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.
