CVE-2026-46599

Name	CVE-2026-46599
Description	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.
Source	CVE (at NVD; CERT, ENISA, LWN, oss-sec, fulldisc, Debian ELTS, Red Hat, Ubuntu, Gentoo, SUSE bugzilla/CVE, GitHub advisories/code/issues, web search, more)
