The overflow causes the bounds-check guard expression to wrap to INT_MIN, bypassing the PARSE_BUF_SIZE comparison and invoking memcpy() with attacker-controlled data into a heap buffer, resulting in an out-of-bounds heap write and potential memory corruption or code execution.","severity":{"version":"4.0","score":8.5,"vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","level":"high","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-10","score":0.00145,"percentile":0.03797,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":true},"cwes":["CWE-190","CWE-787"],"published":"2026-08-06T21:24:15Z","modified":"2026-10-28T11:01:26Z","fixes":[{"ecosystem":"Debian:14","package":"ffmpeg","fixed_in":["7:9.0.2-1"],"sources":["osv"]},{"ecosystem":"Julia","package":"FFMPEG_jll","fixed_in":["9.0.0+0"],"sources":["osv"]},{"ecosystem":"Julia","package":"FFMPEG_nogpl_jll","fixed_in":["9.0.0+0"],"sources":["osv"]},{"ecosystem":"Julia","package":"FFplay_jll","fixed_in":["9.0.0+0"],"sources":["osv"]},{"ecosystem":"Ubuntu:Pro:16.04:LTS","package":"ffmpeg","fixed_in":["7:2.8.17-0ubuntu0.1+esm16"],"sources":["osv"]},{"ecosystem":"Ubuntu:Pro:18.04:LTS","package":"ffmpeg","fixed_in":["7:3.4.11-0ubuntu0.1+esm14"],"sources":["osv"]},{"ecosystem":"Ubuntu:Pro:20.04:LTS","package":"ffmpeg","fixed_in":["7:4.2.7-0ubuntu0.1+esm15"],"sources":["osv"]},{"ecosystem":"Ubuntu:Pro:22.04:LTS","package":"ffmpeg","fixed_in":["7:4.4.2-0ubuntu0.22.04.1+esm14"],"sources":["osv"]},{"ecosystem":"Ubuntu:Pro:24.04:LTS","package":"ffmpeg","fixed_in":["7:6.1.1-3ubuntu5+esm12"],"sources":["osv"]},{"ecosystem":"Ubuntu:Pro:26.04:LTS","package":"ffmpeg","fixed_in":["7:8.0.1-3ubuntu2+esm3"],"sources":["osv"]}],"affected":[{"source":"osv","ecosystem":"Debian:12","package":"ffmpeg","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","7:9.0.2-1"]},{"source":"osv","ecosystem":"Debian:13","package":"ffmpeg","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","7:9.0.2-1"]},{"source":"osv","ecosystem":"Debian:14","package":"ffmpeg","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7:9.0.2-1"}]}],"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"]},{"source":"osv","ecosystem":"Julia","package":"FFMPEG_jll","ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"9.0.0+0"}]}]},{"source":"osv","ecosystem":"Julia","package":"FFMPEG_nogpl_jll","ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"9.0.0+0"}]}]},{"source":"osv","ecosystem":"Julia","package":"FFplay_jll","ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"9.0.0+0"}]}]},{"source":"osv","ecosystem":"Mageia:10","package":"ffmpeg","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.1.5-1.1.mga10"}]}],"bundled":25},{"source":"osv","ecosystem":"Mageia:10","package":"ffmpeg","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.1.5-1.1.mga10.tainted"}]}],"bundled":25},{"source":"osv","ecosystem":"openEuler:22.03-LTS-SP4","package":"ffmpeg","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.2.4-54.oe2203sp4"}]}],"bundled":4},{"source":"osv","ecosystem":"openEuler:24.03-LTS-SP1","package":"ffmpeg","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.1.1-48.oe2403sp1"}]}],"bundled":3},{"source":"osv","ecosystem":"openEuler:24.03-LTS-SP3","package":"ffmpeg","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.1.1-48.oe2403sp3"}]}],"bundled":3},{"source":"osv","ecosystem":"openEuler:20.03-LTS-SP4","package":"ffmpeg","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.2.4-54.oe2003sp4"}]}],"bundled":4},{"source":"osv","ecosystem":"openEuler:24.03-LTS-SP4","package":"ffmpeg","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.1.1-49.oe2403sp4"}]}],"bundled":10},{"source":"osv","ecosystem":"SUSE:Linux

The tdsc_parse_tdsf() function fails to unreference the existing reference frame before calling av_frame_get_buffer(), causing tdsc_blit() and tdsc_yuv2rgb() to write attacker-controlled pixel data beyond the end of the undersized reference frame buffer, resulting in a process crash and potential code execution.(CVE-2026-65703)\n\nFFmpeg 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.(CVE-2026-65705)\n\nFFmpeg versions from 0.5 up to, but not including, 9.0 contain a signed integer overflow vulnerability in the DVB subtitle parser in libavcodec/dvbsub_parser.c that allows attackers to trigger a heap buffer overflow by supplying a crafted WTV file.

The tdsc_parse_tdsf() function fails to unreference the existing reference frame before calling av_frame_get_buffer(), causing tdsc_blit() and tdsc_yuv2rgb() to write attacker-controlled pixel data beyond the end of the undersized reference frame buffer, resulting in a process crash and potential code execution.(CVE-2026-65703)\n\nFFmpeg 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.

This vulnerability involves a NULL pointer dereference within the `get_min_buffer_size` function when processing specially crafted video files. An attacker could exploit this by providing a malicious video file, leading to a Denial of Service (DoS). A Denial of Service attack prevents legitimate users from accessing a service or resource.(CVE-2026-38344)\n\nA flaw was found in FFmpeg.
