CVE-2026-46599

HIGH 7.5

Excessive resource consumption in PackBits decompression in golang.org/x/image/tiff

CVSS Score

7.5

EPSS Score

0.0%

EPSS Percentile

5th

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.
