golang-golang-x-image: The TIFF decoder does not place a limit on the size of PackBits-compressed data
CVE-2026-46599 is fixed in 2 products on 1 platform, first by DEBIAN-CVE-2026-46599, released May 29, 2026. It is not reported as exploited. Patch Radar priority: High.
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.
