{"id":"UBUNTU-CVE-2026-119719","details":"Blender before 4.5.15 and 5.x before 5.2.3 contains a heap buffer overflow vulnerability in the blend file thumbnail extractor caused by 32-bit integer overflow in thumb_data_vertical_flip(). Attackers can craft a .blend file with malicious TEST block dimensions that trigger an out-of-bounds write when blender-thumbnailer or the Windows shell extension previews it, causing crashes or code execution.","modified":"2026-11-04T03:30:32.467941942Z","published":"2026-11-03T00:00:00Z","upstream":["CVE-2026-119719"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-119719"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-119719"},{"type":"REPORT","url":"https://projects.blender.org/blender/blender/pulls/164279"},{"type":"REPORT","url":"https://projects.blender.org/blender/blender/commit/d723c68112d216099c9b24dab5c8440bab7add08"},{"type":"REPORT","url":"https://projects.blender.org/blender/blender/commit/71c10a0217d5e331b215b76773ad23b64974bd97"},{"type":"REPORT","url":"https://projects.blender.org/blender/blender"},{"type":"REPORT","url":"https://projects.blender.org/blender/blender/commit/71c10a0217d5e331b215b76773ad23b64974bd97"},{"type":"REPORT","url":"https://projects.blender.org/blender/blender/commit/d723c68112d216099c9b24dab5c8440bab7add08"},{"type":"REPORT","url":"https://www.vulncheck.com/advisories/blender-before-4.5.15-and-5-x-before-5.2.3-heap-buffer-overflow-via-thumbnail-extraction"}],"affected":[{"package":{"name":"blender","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/blender?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.74+dfsg0-4build2","2.75.a+dfsg0-2ubuntu2","2.75.a+dfsg0-2ubuntu3","2.76.b+dfsg0-3","2.76.b+dfsg0-3build1"],"ecosystem_specific":{"binaries":[{"binary_version":"2.76.b+dfsg0-3build1","binary_name":"blender"},{"binary_name":"blender-data","binary_version":"2.76.b+dfsg0-3build1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-119719.json"}},{"package":{"name":"blender","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/blender?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.78.c+dfsg0-2build1","2.79+dfsg0-2build1","2.79+dfsg0-3","2.79+dfsg0-3build1","2.79.b+dfsg0-1","2.79.b+dfsg0-1ubuntu1.18.04.1"],"ecosystem_specific":{"binaries":[{"binary_name":"blender","binary_version":"2.79.b+dfsg0-1ubuntu1.18.04.1"},{"binary_name":"blender-data","binary_version":"2.79.b+dfsg0-1ubuntu1.18.04.1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-119719.json"}},{"package":{"name":"blender","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/blender?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.80+dfsg-3","2.80+dfsg-3build1","2.80+dfsg-4","2.81.a+dfsg-5build3","2.82+dfsg-1","2.82+dfsg-1build1","2.82.a+dfsg-1"],"ecosystem_specific":{"binaries":[{"binary_name":"blender","binary_version":"2.82.a+dfsg-1"},{"binary_name":"blender-data","binary_version":"2.82.a+dfsg-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-119719.json"}},{"package":{"name":"blender","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/blender?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.93.3+dfsg-3","2.93.5+dfsg-1","2.93.5+dfsg-1build1","3.0.1+dfsg-7"],"ecosystem_specific":{"binaries":[{"binary_version":"3.0.1+dfsg-7","binary_name":"blender"},{"binary_name":"blender-data","binary_version":"3.0.1+dfsg-7"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-119719.json"}},{"package":{"name":"blender","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/blender?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.6.2+dfsg-2ubuntu1","3.6.2+dfsg-2ubuntu2","4.0.2+dfsg-1ubuntu1","4.0.2+dfsg-1ubuntu2","4.0.2+dfsg-1ubuntu4","4.0.2+dfsg-1ubuntu6","4.0.2+dfsg-1ubuntu7","4.0.2+dfsg-1ubuntu8"],"ecosystem_specific":{"binaries":[{"binary_version":"4.0.2+dfsg-1ubuntu8","binary_name":"blender"},{"binary_name":"blender-data","binary_version":"4.0.2+dfsg-1ubuntu8"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-119719.json"}},{"package":{"name":"blender","ecosystem":"Ubuntu:26.10","purl":"pkg:deb/ubuntu/blender?arch=source&distro=stonking"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.0.1+dfsg-1ubuntu1","5.0.1+dfsg-1ubuntu3","5.0.1+dfsg-3build1","5.0.1+dfsg-5"],"ecosystem_specific":{"binaries":[{"binary_name":"blender","binary_version":"5.0.1+dfsg-5"},{"binary_name":"blender-data","binary_version":"5.0.1+dfsg-5"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-119719.json"}},{"package":{"name":"blender","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/blender?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.3.2+dfsg-2ubuntu2","5.0.1+dfsg-1ubuntu1"],"ecos
