CVE-2026-46599
golang.org/x/image/tiff has excessive resource consumption in PackBits decompression
Impact
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.
