CVE-2024-24792Public exploitNetwork attack vector

Service crash via unchecked palette index

Published Jun 27, 2024 · Updated Aug 1, 2024

Improper palette-index validation in golang.org/x/image/tiff before 0.18.0 allows remote attackers to crash image-processing services. The paletted-image branch of decoder.decode passes each decoded color index to image.Paletted.SetColorIndex without checking it against the palette length. Exploitation requires a consuming application to call Decode on an attacker-controlled TIFF and later access a pixel whose index lies outside the actual palette.
