{"id":"UBUNTU-CVE-2022-48434","details":"libavcodec/pthread_frame.c in FFmpeg before 5.1.2, as used in VLC and other products, leaves stale hwaccel state in worker threads, which allows attackers to trigger a use-after-free and execute arbitrary code in some circumstances (e.g., hardware re-initialization upon a mid-video SPS change when Direct3D11 is used).","modified":"2026-04-22T13:33:01.588767Z","published":"2023-03-29T17:15:00Z","related":["USN-6449-1"],"upstream":["CVE-2022-48434"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2022-48434"},{"type":"REPORT","url":"https://git.ffmpeg.org/gitweb/ffmpeg.git/commit/cc867f2c09d2b69cee8a0eccd62aff002cbbfe11"},{"type":"REPORT","url":"https://git.ffmpeg.org/gitweb/ffmpeg.git/commit/35aa7e70e7ec350319e7634a30d8d8aa1e6ecdda"},{"type":"REPORT","url":"https://wrv.github.io/h26forge.pdf"},{"type":"REPORT","url":"https://news.ycombinator.com/item?id=35356201"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-6449-1"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2022-48434"}],"affected":[{"package":{"name":"ffmpeg","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/ffmpeg@7:2.8.17-0ubuntu0.1+esm14?arch=source&distro=esm-apps/xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["7:2.7.2-1build1","7:2.8.1-1ubuntu1","7:2.8.2-1ubuntu1","7:2.8.3-1","7:2.8.4-1","7:2.8.4-1ubuntu1","7:2.8.4-1ubuntu2","7:2.8.4-1ubuntu3","7:2.8.4-1ubuntu4","7:2.8.6-1ubuntu1","7:2.8.6-1ubuntu2","7:2.8.8-0ubuntu0.16.04.1","7:2.8.10-0ubuntu0.16.04.1","7:2.8.11-0ubuntu0.16.04.1","7:2.8.14-0ubuntu0.16.04.1","7:2.8.15-0ubuntu0.16.04.1","7:2.8.15-0ubuntu0.16.04.1+esm1","7:2.8.17-0ubuntu0.1","7:2.8.17-0ubuntu0.1+esm1","7:2.8.17-0ubuntu0.1+esm2","7:2.8.17-0ubuntu0.1+esm3","7:2.8.17-0ubuntu0.1+esm4","7:2.8.17-0ubuntu0.1+esm5","7:2.8.17-0ubuntu0.1+esm6","7:2.8.17-0ubuntu0.1+esm7","7:2.8.17-0ubuntu0.1+esm8","7:2.8.17-0ubuntu0.1+esm9","7:2.8.17-0ubuntu0.1+esm10","7:2.8.17-0ubuntu0.1+esm11","7:2.8.17-0ubuntu0.1+esm12","7:2.8.17-0ubuntu0.1+esm13","7:2.8.17-0ubuntu0.1+esm14"],"ecosystem_specific":{"binaries":[{"binary_name":"ffmpeg","binary_version":"7:2.8.17-0ubuntu0.1+esm14"},{"binary_name":"libav-tools","binary_version":"7:2.8.17-0ubuntu0.1+esm14"},{"binary_name":"libavcodec-extra","binary_version":"7:2.8.17-0ubuntu0.1+esm14"},{"binary_name":"libavcodec-ffmpeg-extra56","binary_version":"7:2.8.17-0ubuntu0.1+esm14"},{"binary_name":"libavcodec-ffmpeg56","binary_version":"7:2.8.17-0ubuntu0.1+esm14"},{"binary_name":"libavdevice-ffmpeg56","binary_version":"7:2.8.17-0ubuntu0.1+esm14"},{"binary_name":"libavfilter-ffmpeg5","binary_version":"7:2.8.17-0ubuntu0.1+esm14"},{"binary_name":"libavformat-ffmpeg56","binary_version":"7:2.8.17-0ubuntu0.1+esm14"},{"binary_name":"libavresample-ffmpeg2","binary_version":"7:2.8.17-0ubuntu0.1+esm14"},{"binary_name":"libavutil-ffmpeg54","binary_version":"7:2.8.17-0ubuntu0.1+esm14"},{"binary_name":"libpostproc-ffmpeg53","binary_version":"7:2.8.17-0ubuntu0.1+esm14"},{"binary_name":"libswresample-ffmpeg1","binary_version":"7:2.8.17-0ubuntu0.1+esm14"},{"binary_name":"libswscale-ffmpeg3","binary_version":"7:2.8.17-0ubuntu0.1+esm14"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2022/UBUNTU-CVE-2022-48434.json"}},{"package":{"name":"ffmpeg","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/ffmpeg@7:3.4.11-0ubuntu0.1+esm3?arch=source&distro=esm-apps/bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7:3.4.11-0ubuntu0.1+esm3"}]}],"versions":["7:3.3.4-2","7:3.3.4-2build3","7:3.4-2ubuntu2","7:3.4-4","7:3.4-4build1","7:3.4.1-1","7:3.4.1-1build1","7:3.4.2-1","7:3.4.2-1build1","7:3.4.2-2","7:3.4.4-0ubuntu0.18.04.1","7:3.4.6-0ubuntu0.18.04.1","7:3.4.8-0ubuntu0.2","7:3.4.11-0ubuntu0.1","7:3.4.11-0ubuntu0.1+esm1","7:3.4.11-0ubuntu0.1+esm2"],"ecosystem_specific":{"availability":"Available
