Attackers can supply a crafted .blend file with short blocks so field reads, writes, and pointer dereferences overrun heap memory, causing crashes or code execution.","cvssScore":7.8,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","cwes":["CWE-125"],"vendors":[],"products":[],"references":[{"url":"https://projects.blender.org/blender/blender","tags":[]},{"url":"https://projects.blender.org/blender/blender/commit/7de4986e74ed47f67e78eb4b76609bb6d1ae8a0e","tags":[]},{"url":"https://projects.blender.org/blender/blender/commit/c5d6faf04bf3f17efb6c404896ef0e7427784da5","tags":[]},{"url":"https://projects.blender.org/blender/blender/pulls/164279","tags":[]},{"url":"https://www.vulncheck.com/advisories/blender-before-4.5.15-and-5-x-before-5.2.3-heap-out-of-bounds-access-via-read-struct","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
