{"id":"DEBIAN-CVE-2026-3650","details":"A memory leak exists in the Grassroots DICOM library (GDCM). The bug occurs when parsing malformed DICOM files with non-standard VR types in file meta information. The vulnerability leads to vast memory allocations and resource depletion, triggering a denial-of-service condition. A maliciously crafted file can fill the heap in a single read operation without properly releasing it.","modified":"2026-09-14T17:03:29.312419635Z","published":"2026-03-26T22:16:31.370Z","upstream":["CVE-2026-3650"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-3650"}],"affected":[{"package":{"name":"gdcm","ecosystem":"Debian:12","purl":"pkg:deb/debian/gdcm?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.0.21-1","3.0.21-2","3.0.22-1","3.0.22-2","3.0.22-2.1","3.0.22-2.1~exp1","3.0.22-3","3.0.24-1","3.0.24-1+hurd.1","3.0.24-10","3.0.24-11","3.0.24-12","3.0.24-13","3.0.24-14","3.0.24-2","3.0.24-3","3.0.24-3+hurd.1","3.0.24-4","3.0.24-5","3.0.24-5+hurd.1","3.0.24-5+hurd.2","3.0.24-6","3.0.24-7","3.0.24-8","3.0.24-9"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-3650.json"}},{"package":{"name":"gdcm","ecosystem":"Debian:13","purl":"pkg:deb/debian/gdcm?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.0.24-10","3.0.24-11","3.0.24-12","3.0.24-13","3.0.24-14","3.0.24-5","3.0.24-5+hurd.1","3.0.24-5+hurd.2","3.0.24-6","3.0.24-7","3.0.24-8","3.0.24-9"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-3650.json"}},{"package":{"name":"gdcm","ecosystem":"Debian:14","purl":"pkg:deb/debian/gdcm?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.0.24-11"}]}],"versions":["3.0.24-10","3.0.24-5","3.0.24-5+hurd.1","3.0.24-5+hurd.2","3.0.24-6","3.0.24-7","3.0.24-8","3.0.24-9"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-3650.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/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"}]}
