{"id":"DEBIAN-CVE-2026-110734","details":"Godot Engine through 4.7.2 has a heap out-of-bounds write in the Radiance HDR (.hdr) image decoder (modules/hdr/image_loader_hdr.cpp). The run-length decoding loop expands RLE instructions read from the file into a buffer sized from the image dimensions, without validating that an instruction's repeat/copy count fits the remaining capacity of the row buffer. A crafted .hdr file therefore writes attacker-supplied bytes past the end of the heap allocation, with the overflow length and content controlled by the file. The defect is reached automatically when the product imports a crafted .hdr (e.g., when opening a project containing one), and at runtime in exported projects that load untrusted .hdr images. NOTE: the Supplier's position is that the research has identified \"no security issues\" because the required attacker access is outside of the current Godot Engine threat model.","modified":"2026-10-15T18:00:09.715820898Z","published":"2026-10-14T16:17:44.320Z","upstream":["CVE-2026-110734"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-110734"}],"affected":[{"package":{"name":"godot","ecosystem":"Debian:12","purl":"pkg:deb/debian/godot?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.2.3-stable-1","3.5.1-stable-1","3.5.1-stable-2","3.5.2-stable-1","3.5.2-stable-2","3.6+ds-1","3.6+ds-2","4.4.1+ds-1","4.4.1+ds-1.1","4.5.1+ds-1","4.6.3+ds-1","4.6.3+ds-2"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-110734.json"}},{"package":{"name":"godot","ecosystem":"Debian:13","purl":"pkg:deb/debian/godot?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.6+ds-2","4.4.1+ds-1","4.4.1+ds-1.1","4.5.1+ds-1","4.6.3+ds-1","4.6.3+ds-2"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-110734.json"}},{"package":{"name":"godot","ecosystem":"Debian:14","purl":"pkg:deb/debian/godot?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.6+ds-2","4.4.1+ds-1","4.4.1+ds-1.1","4.5.1+ds-1","4.6.3+ds-1","4.6.3+ds-2"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-110734.json"}},{"package":{"name":"godot3","ecosystem":"Debian:14","purl":"pkg:deb/debian/godot3?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.6+ds-3","3.6.1+ds-1","3.6.2+ds-1"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-110734.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:N/I:L/A:N"}]}
