{"id":"DEBIAN-CVE-2026-70652","details":"libvips is a fast image processing library with low memory needs. Prior to version 8.18.3, libvips built with libultrahdr support can incorrectly size an output buffer in libvips/foreign/uhdrsave.c within vips_foreign_save_uhdr_set_raw_hdr when a pipeline enlarges an incoming JPEG to a very large output before encoding a gain map through VipsForeignSaveUhdr. The undersized allocation can cause a heap buffer over-read that may disclose adjacent data or crash the process. This issue is fixed in version 8.18.3.","modified":"2026-10-27T09:47:34.122453349Z","published":"2026-08-20T21:17:08.270Z","upstream":["CVE-2026-70652"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-70652"}],"affected":[{"package":{"name":"vips","ecosystem":"Debian:14","purl":"pkg:deb/debian/vips?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"8.18.3-1"}]}],"versions":["8.16.1-1","8.16.1-2","8.17.3-1","8.17.3-2","8.18.0-1","8.18.0-2","8.18.0-3","8.18.1-1","8.18.2-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-70652.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:H/AT:N/PR:L/UI:N/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}
