{"id":"DEBIAN-CVE-2026-65705","details":"FFmpeg versions 3.4 through 8.1.2 contain an out-of-bounds write vulnerability in the vf_floodfill video filter that allows attackers to corrupt heap memory by supplying a dynamically sized video stream with filtergraph reinitialization disabled via -reinit_filter 0. When config_input() allocates the points traversal stack based on initial frame dimensions and a subsequent larger frame is processed, filter_frame() performs flood-fill neighbor pushes beyond the original allocation boundary, resulting in heap corruption and process crash with potential for code execution depending on heap layout and process hardening.","modified":"2026-09-01T16:06:56.653714203Z","published":"2026-07-23T20:17:22.120Z","upstream":["CVE-2026-65705"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-65705"}],"affected":[{"package":{"name":"ffmpeg","ecosystem":"Debian:12","purl":"pkg:deb/debian/ffmpeg?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["7:5.1.3-1","7:5.1.3-2","7:5.1.4-0+deb12u1","7:5.1.5-0+deb12u1","7:5.1.6-0+deb12u1","7:5.1.7-0+deb12u1","7:5.1.8-0+deb12u1","7:5.1.9-0+deb12u1","7:6.0-1","7:6.0-2","7:6.0-3","7:6.0-4","7:6.0-5","7:6.0-6","7:6.0-7","7:6.0-8","7:6.0-9","7:6.1-1","7:6.1-2","7:6.1-3","7:6.1-4","7:6.1-5","7:6.1.1-1","7:6.1.1-2","7:6.1.1-3","7:6.1.1-4","7:6.1.1-5","7:7.0-1","7:7.0.1-1","7:7.0.1-2","7:7.0.1-3","7:7.0.1-4","7:7.0.1-5","7:7.0.2-1","7:7.0.2-2","7:7.0.2-3","7:7.1-1","7:7.1-2","7:7.1-3","7:7.1-4","7:7.1.1-1","7:7.1.2-1","7:7.1.3-1","7:8.0-1","7:8.0-2","7:8.0.1-1","7:8.0.1-2","7:8.0.1-3","7:8.1-1","7:8.1-2","7:8.1-3","7:8.1.1-1","7:8.1.1-2","7:8.1.1-3","7:8.1.1-4","7:8.1.2-1","7:8.1.2-2","7:9.0-1","7:9.0.1-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-65705.json"}},{"package":{"name":"ffmpeg","ecosystem":"Debian:13","purl":"pkg:deb/debian/ffmpeg?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["7:7.1.1-1","7:7.1.2-0+deb13u1","7:7.1.2-1","7:7.1.3-0+deb13u1","7:7.1.3-1","7:7.1.4-0+deb13u1","7:7.1.5-0+deb13u1","7:8.0-1","7:8.0-2","7:8.0.1-1","7:8.0.1-2","7:8.0.1-3","7:8.1-1","7:8.1-2","7:8.1-3","7:8.1.1-1","7:8.1.1-2","7:8.1.1-3","7:8.1.1-4","7:8.1.2-1","7:8.1.2-2","7:9.0-1","7:9.0.1-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-65705.json"}},{"package":{"name":"ffmpeg","ecosystem":"Debian:14","purl":"pkg:deb/debian/ffmpeg?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["7:7.1.1-1","7:7.1.2-1","7:7.1.3-1","7:8.0-1","7:8.0-2","7:8.0.1-1","7:8.0.1-2","7:8.0.1-3","7:8.1-1","7:8.1-2","7:8.1-3","7:8.1.1-1","7:8.1.1-2","7:8.1.1-3","7:8.1.1-4","7:8.1.2-1","7:8.1.2-2","7:9.0-1","7:9.0.1-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-65705.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:P/VC:H/VI:H/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"}]}
